Seems a fair question to ask someone who makes a post to direct people away from a service under the presumption that they were trying to use it, only to find in the comments that they already use a different service that they not only enjoy, but are happy to freely advertise for.
Also, your justification for their lack of crypto payments is that they use a payment system they designed themselves, which I find funny since most of the complaints I see about Proton (granted, not yours) is the unverifiability of their operations, leaning on "Just trust me, bro." which is the same thing as this site's payment processing system. 🤭
