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.
When you activate the HP+, HP permanently disables the printer's ability to use 3rd party ink. Model numbers that end in "e" require HP+ to function. While other model numbers don't require HP+, someone who is not already aware of it could be prompted into signing up for it without understanding they're permanently disabling their ability to use third party ink.
