Here's a good summary and legal analysis by noyb:
They warm up things that a) I don't want to put in a kettle and b) don't want to put in a dedicated pot to put on the stove.
Like the remainder of the soup i made yesterday that I've put in a china bowl in the fridge. I was able to eat warm soup out of that bowl without requiring to make any other dishes dirty. Pretty convenient if you ask me.
Bonus: you can take a cherry tomato or a single grape and make a small plasma arc in the microwave. Pretty cool trick to impress and scare people at house parties.

Their track record is pretty good.
the issue was never the law.
the issue were the 100s of tracking cookies and that websites would use dark patterns or simply not offer a "no to all" button at all (which is against the law, btw.)
Most websites do. not. need. cookies.
It's all about tracking and surveillance to show you different prices on airbnb and booking.com to maximise their profits.
