I’ll start: printers.
I bought an HP in March 2020 when my job went remote and HP bricked it remotely after only 100 pages because I wouldn’t sign up for their subscription program. Ended up trashing a perfectly good printer.
Luckily my library’s close by and I can print there remotely.
The Samsung IR app also was used for their streaming service. They could have easily updated the app to allow it to run without connecting to their servers once they killed the service, but it was easier to tell their customers to pound sand.
