I'm surprised so many replies here are about removing a free tier 2 years ago. Things cost money, what did you expect? Whenever I get free products that cost money I expect it's either temporary, or I'm being the product myself.

I think the longevity of Gmail, Youtube etc being both (a) absolutely free and (b) personally critical to many people has rather warped expectations in this regard. Take the freebie, be grateful, but don't imagine that giving no money to a corporation is going to incur any obligation from them to you.
