Of course it’s the website fault, but just like government don’t let companies do whatever they want (all the time) the have to force websites to not do certain things, a warning certainly doesn’t do much when people keep clicking “accept”.
It’s the EU’s fault that there is that warning in the pages, a warning that doesn’t fix the real problem, just puts a sign on it.
“WET FLOOR!” instead of fixing the leaking pipe.
My tip is don’t obsess too much about if you’ll find replacement for this software or that software, the moment you’ll need it you’ll try and you will definitively find alternatives BUT it will take time to get used to it and it’s the way it is.
The more you stay on the new system the easier it will be. I switched my desktop recently and I had the temptation of going back but I stuck to it and now I don’t have the temptation, but I need windows for stupid whatsapp videocalls though (there are alternatives but the other person isn’t tech savvy and I want to make things easier)
