You're using a web browser built by a company whose primary income is advertising. What did you think would happen instead?
A lot of people have this weird idea that companies are their friends and would defend their interests despite large financial incentives to betray that trust.
What do you think uBlock Lite is for? They'll continue to cripple it until it is unable to block YouTube ads while still being able to block everything else.
Financial incentives, while a large motivator for companies, are frequently not the exclusive one.
Google for quite a few years was seen as a good steward of the free and open Internet.
To assert people shouldn't feel betrayed because "it's a company" fundamentally ignores why people had different expectations for Google to begin with.
Because it was in their financial interest to do so. Their business is dependent on the internet after all.
The problem is that people are quick to assume a company is being altruistic just because the financial incentives happen to align with their own incentives.
This is a parallel argument to the whole "to big to fail" nonsense and not really in line with the famous comparison of a single person to a machine. Company strategies are typically created by small groups of people who - especially in this case - know exactly what the impact and longer-reach implications of their decisions will be. It is entirely reasonable to hold the people of any organization accountable for the policies they enact via that organization.
Firefox has had poor stewardship for quite a few years now with an uncertain future.
Even moreso - uBlock Origin doesn't block the modern equivalent of pop-up ads unless you manually block elements. Even then - half the time the block isn't even saved and needs to be redone every page visit.
