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. ๐คญ
Instead of being so defensive about it you could just answer the question.. Did you have so much free time you decided to try signing up for a service you had no intention of using just so you could complain about it?
