So them saving users a Google Search for the alternatives was all it took to clear them? Damn, if only big G had known, they could have saved themselves a lot of flak.
(Actually, it wouldn't have mattered. Don't kid yourself.)
Yes, but that's not really Google's responsibility.
They deliberately gave a three month sunset for users to find another solution. That's entirely the point of a sunset.
Their product is also free, so it's not like they're hurting businesses or real customers by not helping them find alternatives. They're not really obligated to even do anything at all - it was a free service. If they were being paid it would make more sense.
I believe we can reasonably hold them to it. You can't just shut off the lights to a product that people pay for (well, you could, but that's a liability).
