Though as part of the signup I'm asked for a credit card. So it's not really "free". It's for credit card users only that need to trust they won't charge you.
I believe they address this on the last sentence of the blog as a measure to prevent abuse on the free-tier they ask for credit card info, they specifically complain about cypto mining
Thanks for that. I actually went to the blog to read it and you're right they do explain themselves. Thank you.
I like cryptomining, so it doesn't help my adoption of them.
OK I'm not sure why the downvotes. I don't want to enter a credit card to access a "free service".
