Because you cannot even control your ads to users? No one of you devs gets punishment for tracking users' personal information, pushing scam, phishing and malware to users, and now users are not even allowed to protect themselves? Users don't drop trackers and malwares to your servers, why do you drop trackers and malwares to users' machines?
Because you are working for a corporation that joins in World Wide Web Consortium, who literally says this in the Ethical Web Principles?
> People must be able to change web pages according to their needs. For example, people should be able to install style sheets, assistive browser extensions, and blockers of unwanted content or scripts. We will build features and write specifications that respect people's agency, and will create user agents to represent those preferences on the web user's behalf.

If you cannot maintain your service, paywall your features, not forcing malwares and trackers to users. No one forced you to serve 1080p, 1440p or 4K videos to everyone for free. You were the one literally "advertised" yourself as a "free" service at beginning, in order to hoard how many users you could. And now when you cannot control your own costs, you push malwares and trackers to users? The mentality of hoarding users with "baits" like "free" are the real poisons for the internet, for both of you and your users, NOT users who are doing exactly what World Wide Web Consortium tells them.
Where are all your MBAs in your corporations? The ones bragging about themselves on LinkedIn and now the only resolutions you can think of is pushing malwares and trackers to users? All of the finance classes in your college should be simplified to advertisement classes I guess? That would save a lot of resources for everyone.
