Calling it a boring meme is condescending. It's dismissing people's concerns as a joke they made up for attention, rather than addressing and refuting their actual argument.
Linking to killedbygoogle.com where more than half of things are not actually kiled by Google is not a good argument. I agree that products getting killed by Google is a concern and a few comment accurately point out and add to discussions while most of the others just keep repeating like a meme. Very rarely the discussion feels like a discussion.
OP brought up another point about Google being a 20 year old company so you are ought to see lot of products being shut down over the time. While the reply had nothing to do with that but instead resorted to ad hominem attack.
