This is my take too - Google Search and YouTube especially which are owned by Google.
Even if Chrome had like 5% market share, surely they could just push this anyway? While the Chromium monopoly is partially to blame for this, I'd argue the centralisation of the web is as well.
Sure, "Google Search is useless now, you can't find what you want!", but the vast, vast majority of people still and continue to use it, and nothing will change that most likely.
For what it's worth I'm not saying that - it's just a common argument I've seen online lately in these spaces. I don't actually know if it's true because I don't use Google Search.
