Basically, I think he's saying that Google and Youtube have altered their search algorithms to bias towards progressive values and demote (rank lower) non-progressive posts.
Also, he's saying people have had their accounts cancelled because their accounts were flagged as "hate speech" (even if it wasn't) and that doing so, was biased.
Also, some companies are aggressively forcing their employees to subscribe and support certain political ideas. I won't name names, but I've also felt this at one place I worked. Here's how it works. Managers engage their subordinates on political matters, asking them "what they think". And if you don't agree with their views, you may be negatively sanctioned, in the future (this is implied, not specifically spelled out).
I felt like that at my previous job(startup) everyone was very progressive and if you disagreed with any progressive ideologies you would be socially shunned.
Being rather moderate (which is a republican in my state and I am slightly left of them) and a skeptic you would only be ostracized for thinking anything but what Bernie Sanders or Elizabeth Warren preaches. No one likes someone who questions everything because they see politics as akin to faith.
This propensity to ostracize people only pushes them further away from center because they will only discuss things with people who won't shame them and of course that will be online.
Now I work at a financial firm and we have a lot of liberals and republicans and they are all willing to speak their mind because politics here has nothing to do with who your friends are.
