I have been a heavy user of Claude but cancelled my Pro subscription yesterday. The usage limits have been quietly tightened up like crazy recently and 3.7 is certainly feeling dumber lately.
But the main reason I quit is the constant downtime. Their status page[0] is like a Christmas tree but even that only tells half the story - the number of times I have input a query only to have Claude sit, think for a while then stop and return nothing as if I had never submitted at all is getting ridiculous. I refuse to pay for this kind of reliability.
