Both auto-forwarding and auto-reply are paid features, which makes cancelling & switching much more difficult. Gmail is a breeze comparatively. I highly recommend against using their addresses (e.g. protonmail.com, proton.me, pm.me)
Email forwarding is available for everyone with a paid Proton Mail plan.

No, Proton email addresses do not. I have ProtonMail addresses using my domain. If tomorrow I point to another email provider, Proton can do nothing about it.
Being paid feature vs free is not vendor lock-in.
You are spreading misinformation, either by misrepresenting the situation or by not understanding what “vendor” (an arguable term since apparently you are focusing on the free version) is lock-in means.
I think OP is overblowing things, and is especially misguided in recommending gmail, but at the same time, they do have a valid point and I think you’re somewhat misrepresenting what they said.
For one, they specifically said that the proton domain email addresses are problematic (
protonmail.com,pm.me), and weren’t talking about custom domains that sit in front of Proton mail.For two, their point is valid. Auto-forwarding being paid, does create vendor lock-in and make it hard to switch away from Protonmail if you use the OOTB addresses. It’s something worth considering.
As you said, the recommendation should be to use a custom domain that sits in front of Protonmail rather than switching to Gmail, but paid auto-forwarding is a valid criticism.
if you’re not actually promoting gmail, you ought to make that explicitly clear.
by pointing out something bad about proton and praising gmail’s version of that, it looks like you’re doing nothing other than recommending gmail in a privacy community.
everyone already knows gmail has high usability and convenience and zero (financial) cost. using it as an example in this community is redundant and ineffective. better to use another e2ee email service as an example.
