Trump wants to use social media to spread his lies and misinformation. Then when his posts get fact-checked, he complains about freedom of speech. He claims that conservative views are suppressed.
Or when the alt-right spreads hate-filled bile, they get removed from social media- Trump complains that right-wing views are being suppressed.
If someone was left-wing and they were spewing the same BS as the far alt-right, they would also be removed from social media.
Trump is happy to use social media to push conspiracy theories, lie and pushing his misinformation . He does not want to be challenged, and suddenly freedom of speech must be limited...
