As the other commenter said it's about the hardware really. I tested it out on a really old device first to make sure it actually worked - it did but at a glacially slow pace. The new box is pretty snappy though!
Can you not install uBlock Origin on your work machine? I'd argue that it will improve your productivity and reduce the chance of losing the company's info to trackers and the like!
To be fair to those soulless coldblooded monsters it is literally their job to maximise profits, and if they fail they will be replaced with an equivalent bastard
Tangentially related, I recently replaced my Chromecast with a "Chromecast with Google TV". It's an Android TV box which you can install SmartTube on and cast YouTube with no ads. Yes, I am aware of the irony of paying Google for new hardware instead of paying them for their ad-free service, but the new device cost less than 2 months of YouTube Premium and I like tinkering.
Sadly it is still a problem. Fortunately there are some pretty good mobile browsers like Cromite available!
