I was under the impression cyberpunk got that right, generally.
Taken in aggregate, in a world with multi-trillion dollar corporations censor their users, it's not ridiculous to talk about this as tyranny. There is no one tyrant, but every corporation rules like one and taken as a whole, the "world's government" (in this case the set of the most powerful corporations) is tyranny.
Anyway, I'm neither here nor there on the argument, but I don't see what's so laughable about OPs offhand comment.
There are literally hundreds of social media platforms and video hosting sites on the web. Many Youtubers are even advertising their content on alternative platforms.
Being popular is not the same as having a monopoly. Youtube doesn't control infrastructure, they can't prevent users from watching other sites or hosting videos elsewhere. They're not granted special privilege by a government. We've just convinced ourselves for the sake of political narrative that these platforms have far greater power than they actually do.
Once a corporation reaches a certain size, do you really think it’s possible for any other company to overtake it?
There is in fact something stopping them. There are in fact many things stopping them.
When you have $100 billion war chest, are you really going to let someone just walk in and eat your lunch?
Regulatory capture, lobbying, price manipulation, etc., are all things stopping these companies you just referred to, FYI.
Video services are interchangeable. They all have video. They may not have the videos you want to watch, just as other restaurants may not have food you want to eat.
YouTube makes a product. You use that product. No one is forcing you, legally or otherwise, to use it. You can easily not use the product. There are viable competitors to that product. If YouTube stops being good, people will move on to another product.
You cannot, on one hand, remark on how much nicer of an interface YouTube has while also complaining that a change the team which created the superior interface has chosen to make, in hopes of making the interface better, is somehow "tyranny".
You are not a serious person.
