How come every single hardware wallet except ledger doesn't have any similar issues like this?
I can only speak about the devices I have or which I have used for a while, not about what I don't have or know. Trezors function in a different way. You don't install individual crypto apps on them like you do on a Ledger, so it isn't comparable. You enable and disable support for assets through the Trezor Suite.
There is no improvements in shitcoin blockchains, I don't think Doge was ever seriously updated for years, and same thing for bch, so nothing changed.
There is literally zero new features with this bigger size apps...
Again, I can't comment on things I don't know about. What changed with the apps is something you can check personally if you know how to. Ledger's crypto apps are open-source, and many of them are created by the devs of the various crypto projects, not Ledger and their team. I don't have the knowledge to read and understand code and I don't think you have either. Such assessment are better left to those who know. Best case scenario: get someone to do it for you, and prove that they are maliciously inflating the app sizes if you can.
...it's just one more way to force people to switch from model s to other newer models.
As a Ledger Nano S user, it's not working on me. If someone is susceptible by outside factors, it's their problem.
