As always, I was writing a comment to another comment and thought that it might be relevant to create a new (top?) comment itself too (sorry if its "plagiarism")

But basically one other type of such contact pages are when a company has such a contact page + it only works for customers who have logged in and they can only login entirely if they give their credit/debit card info.

I found it to be the case for hetzner,contabo basically. OVH had a discord server which I could join to ask some basic inqueries/support, I never understand the companies which do not have any such things like discord,telegram etc.

In an ideal world I would want them to run matrix or open source but even if they are on discord, it can be light years ahead of the contact page they have right now which I simply don't understand.

I wish to be more anonymous with my credit/debit card info, I recently went into nerding about vps providers basically and signing up via crypto for all its hate was something I enjoyed. (Funny how I linked my previous crypto comments to this contact page idea)

I think ignorance can play a deal in it. I don't think all companies do it out of malice as the article points out, some do it by ignorance. So in a way, Kudos for raising awareness about it.
