This proposal is a terrible joke. Resetting seed phrase is technical non-sense, since different seed phrase leads to different generated address.
We live in a wonderful world where these terrible jokes are almost the norm (considering the absurdity of some laws).
Many HW manufacturers will leave, but it doesn't apply to Ledger who is halfway ready since they already offer Ledger Recover subscription service

.
And given the examples from Ledger, I expect that few manufacturers will "leave" this market, as it would mean a loss of profit. They will adapt to this law and sell this forced service to their customers under the guise of "convenience and some kind of alternative backup". Moreover, I'm even sure that there will be many device buyers who will be satisfied with this feature, just like the Ledger Recover subscription service (paying a subscription fee for strangers to access your wallet- how ingeniously simple!).
This is how people quietly lose their privacy, confidentiality, the sole right to own and manage their assets, and ultimately, financial freedom.
If it is passed, how will companies compensate their customers for any technical problems?
This is certainly not a problem for legislators.

From the perspective of those who propose it, it makes sense, because there are obviously a lot of people who are not capable of keeping their backup safe and don't care (or don't understand) the expression "not your keys, not your coins". For those of us who know what this is about, we wouldn't take such a device even if it were given away.
This is exactly what I'm saying: despite the accessibility and low barrier to entry into the cryptocurrency industry, it turns out that cryptocurrencies aren't for everyone, as not everyone can ensure the necessary level of security for their assets (seed phrase).
I also expect that there is a demand for these
backdoors among cryptocurrency users. As much as we might not like it, some people will be willing to shift responsibility for storing seed phrases to 3rd parties, even risking the safety of their assets.
Despite all the troubles with banks (bankruptcies, thefts by depositors, and losses), the entire world still uses their services (giving your money to strangers is the same as giving away your seed phrase).
Still, I always wonder if we all live under the grand illusion that such devices are secure today and have no backdoor without someone needing to officially tell us?
If I were a HW manufacturer, of course I wouldn't tell anyone about it.

They obviously want full control of everything, and you can see that with all the latest changes with Linux OS, reddit, discord, smartphones, social media, age verification, etc.
It seems a bit absurd (but at the same time it seems like a priority): to want control over something that (cryptocurrencies) allows one to avoid this control.
Luckily we have option to make DIY hardware wallets, and now it's more important than ever to have that available as open source.
Until it's banned yet.

I think in the world of the future, financial freedom will be impossible without it.
