[ti:Unlike Facebook, Twitter Bans Political Advertisements] [by:www.knnrug.live] [00:00.00]更多聽力請訪問51VOA.COM [00:00.04]The heads of two leading social media companies have very different ideas [00:07.48]about paid advertisements supporting political candidates. [00:14.28]On Wednesday, Twitter's Chief Executive Officer (CEO), Jack Dorsey, [00:20.58]said that the social media company would stop all political advertising. [00:28.08]On the same day, Facebook CEO Mark Zuckerberg [00:33.59]again defended his company's policy of permitting political advertisements. [00:41.84]Zuckerberg faced questions on the subject [00:45.78]from lawmakers on the House Financial Services Committee last week. [00:54.08]In a series of tweets, Dorsey said Wednesday [00:58.58]that internet advertising is effective for advertisers. [01:04.56]But he warned: "That power brings significant risks to politics." [01:13.32]Dorsey went on to say that his company believed [01:18.00]that "political message reach should be earned not bought." [01:24.60]He then described what he meant by "message reach." [01:31.28]Dorsey said: "A political message earns reach [01:36.53]when people decide to follow an account or retweet." [01:42.80]He then said, "Paying for reach removes that decision... [01:48.40]forcing political messages on people." [01:54.20]On Twitter, people can follow accounts and retweet messages they find notable. [02:02.84]They also can receive paid messages from advertisers without their approval. [02:11.12]The Associated Press reports that Twitter will offer details about its policy on November 15. [02:21.68]The ban on political advertising is to go into effect on November 22. [02:30.48]The ban will cover ads in support of candidates and ones on political issues. [02:39.28]But Twitter will permit advertisements that support voter registration. [02:47.84]The decision will have a comparatively small effect on Twitter's earnings. [02:55.96]The company's chief financial officer said that the company received less than $3 million [03:04.36]from political advertising during the 2018 elections in the U.S. [03:13.92]The comments from Dorsey were very different from those of Facebook's Zuckerberg. [03:22.16]Facebook announced earlier this month that it would not fact check political ads. [03:30.40]That means the company will not research whether or not the information [03:36.36]presented in political ads is true or not. [03:42.04]It also will not take down ads that may contain false information. [03:50.24]Zuckerberg faced tough questions about the policy while giving testimony to Congress. [03:59.68]Facebook again defended its policy last week saying: [04:04.99]"In a democracy, people should decide what is credible, not tech companies." [04:13.96]Zuckerberg again spoke about the company's decision Wednesday. [04:19.13]He said, "Ads can be an important part of voice – especially for candidates [04:27.33]and advocacy groups the media might not otherwise cover..." [04:33.80]The Facebook chief told shareholders that ads from politicians [04:40.00]would account for less than .5 percent of the company's income next year. [04:49.20]Facebook promised to deal with misinformation on its platform [04:54.70]after the 2016 U.S. presidential election. [05:00.48]At that time, Russian efforts to spread false information [05:06.13]led to several investigations of foreign influence in American elections. [05:14.72]Facebook has periodically taken down pages [05:18.80]suspected of being linked to Russian misinformation efforts. [05:26.80]Many accounts with large numbers of followers on Twitter also are disabled [05:33.84]because, the company says, they do not follow the service's rules. [05:41.44]Some people consider Twitter's policy of not permitting political ads to be better. [05:50.88]Jascha Kaykas-Wolff heads marketing efforts at technology company Mozilla. [05:59.08]He agrees with Twitter's decision to ban political ads. [06:05.08]"Accepting money to run ads that contain falsehoods [06:09.94]isn't the right thing to do for people," he said. [06:15.60]Others say barring political ads will hurt political challengers [06:22.24]who are not recognized by voters. [06:26.40]Matt Shupe is a Republican political advisor who notes that advertising [06:33.74]is an important way for a candidate to gain attention. [06:39.36]He said, "If you're a challenger, advertising allows you to make up that difference." [06:48.24]Twitter's ban on "issue ads" that support one side of a public debate are also a concern. [06:58.64]Ryan Schleeter is a spokesman for the environmental group Greenpeace. [07:06.56]He said he does not want to see companies able to run ads [07:12.41]while "those who confront corporate power are censored." [07:19.60]I'm Mario Ritter Jr. 更多聽力請訪問51VOA.COM 11运夺金走势图遗漏
