My grievances with Proton

banana:

The cost of maintaining an existing alias is actually, factually, absolutely zero

In my response, above, I purposely didn’t quote the cost of anything. Reason being, I’m didn’t see any relevance whatsoever. I still don’t.

Can you expand on the relevance of cost? In inclined to agree, partially, that it probably doesn’t have a significant impact and could be offered for free. But then: why would they? That’s not the deal, so I fail to see any relevance at all to the point being made.

banana:

In the end, there is only the unnecessary restriction of the user of something that is costless on top of what is already provided.

I think this answers everything. The OP requires a paid feature for free. In which case, everything else is entirely moot.

Best wishes…
