Absolutely!
My 1980's tech is repairable, and a fair amount of it is still in active, productive use.
These phones and computers can be made more serviceable. Doing that will reduce profits and that is why it is not being done.
And so we have plenty of people who can figure out how to service the tech anyway! I am one of those types of people and have always explored fixing it no matter what.
(I do not do phones, though I have fixed tablets and computers)
There are always some of us with these skills. Humans are pretty great that way. We are considerably more diverse and capable as an species than we may appreciate.
And what happens?
Of course that lowers profit too!
Now we have right to repair as a thing to be settled because some of us are a bit too greedy for others of us to tolerate.
And regarding phones, my preferred phone is falling out of support. It had a headphone jack and performance is right there, sans a faster than 60hz display, which is no bother. Grew up with 60. Love it, but I digress.
I need to be careful with this phone, and that is fine. Keeps me from doing too much crap on it and that helps me be more productive and less tied to the thing. No worries yet.
Now, I have two of these. One has a cracked glass and a battery not long for this world. When I want, I hook it up to keyboard, mouse and display and it works great! Perfectly fine Android PC. I may start building some software for it too.
But, as it is right now, email, remote conferencing, Libre Office, Microsoft if needed, CAD, STL file, bitmap create, edit, Web, and, and...
I forget what the CPU is, but this old, glass cracked phone runs a Snapdragon fast enough to beat some Chromebooks I have gotten hold of.
Definitely worth winning Right To Repair. The up and coming generations are going to face a lot of challenges, and being economically challenged is, sadly, among the set of challenges.
My generation was similar, Gen-X. I grew up in fairly severe poverty. Fortunately, was not my entire childhood, but it was more than half. Made an impact, and the primary one was whether to spend to solve or repair to solve problems, and there is a ton of perfectly great tech laying around today.
It is crazy to be figuring out how we best avoid using it!
My 1980's tech is an Apple 2 computer. I still use it regularly. Mostly games, Nox Archaist released recently being top of the list. (If passers by enjoy "Ultima" style gaming, you can buy this title right off GOG and or Steam and play in emulation.)
But, yes I use it as a spiffy calculator, generating datasets of various kinds, terminal to embedded devices and when I get off my arse and finish my test and measure card, it will be a great bench computer just as it was back then.
Finally, as RMS has said about software freedoms, it is not important that people use those freedoms to the max. Many won't, and that is OK.
This is all about the people who will, or better --who have to for whatever reason.
It just needs to be possible.
