You’ve missed the point, so I assume you haven’t been following any of this and commented without bothering trying to.
The main complaint isn’t about not being able to open accounts online — it’s about foreigners being completely excluded from opening accounts at all (LINE Bank and most of the others) or from specific services and promotions (as in this case with Richart/Taishin).
Going into a bank to open an account is irrelevant to this. That isn’t something I complained about and wouldn’t have helped here because foreigners aren’t/weren’t allowed to sign up at all. That’s just something the banks/government agencies wrote to justify their discrimination (the claim being they can’t be discriminatory because they deign to provide other services to foreigners and don’t exclude us completely).
Again, you’ve missed the point. This is irrelevant here because foreigners are excluded irrespective of what ID they have. In any case, they should be able to use our Taiwan-issued A(P)RCs and NHI cards, driving licenses, etc. Instead they’ve just chosen to say “no foreigners”.
