If I understand correctly, they are literally giving things away for free for a 6 months period and we are complaining that they don't promise it stays free forever?
No, you did not understand correctly. They are not “literally giving things away for free”, they are providing a very conditional free trial, which is a business decision and not anything new. Then a commenter speculated they might extend that program because they didn’t say they won’t and I pointed out it doesn’t make sense to assume they will. No one on this immediate thread made any complaint, we’re discussing the facts of the offering.
