Then it means all wallets are equal here, if I use this Ledger wallet and something funny happens one day from the dev side what's going to happen? Isn't this one of the reasons why people avoid mobile wallets like trust wallet and coinomi?.
Actually it's not the same.
Trust wallet/coinomi create and send the transactions. Most people use those wallets without HW, so no safety net at all.
On the other hand, hardware wallet "only" signs the transactions. If one uses Ledger (one of the bad examples), he can use it with Electrum, for example. With the correct settings Electrum will show every step done.
Can Ledger do bad things after a certain update? Probably (but after that bye-bye business). Will Electrum "play along"? I hope not. Of course, if one also uses Ledger Live, he's more exposed.
Also while Trust wallet or coinomi basically doesn't risk anything if they do something fishy (no liability), a business that makes hardware wallets is basically gone after that and also faces lawsuits to recover those funds.
All in all, you do have a point, I don't deny that, just it's not entirely correct.
