Earlier quoted context omitted.
Like I mentioned, don’t use google products then. What’s the value of spamming this all of the time? The validity of the concern isn’t the problem, it’s the fact that it’s irrelevant to the content being posted.
To warn users so they're aware that the lifespan of the product they're using may be very short, and therefore they may lose something they put a lot of investment in. It's empathy.
The thing is, these repetitive comments get spammed dozens of times on every Google-related post. They could be posted without reading the submission. Many of them probably are in fact probably posted just based on the title (seeing how many people posted basically exactly the same comments into a submission today that wasn't even about a product). These comments completely crowd out any other discussion just due to sheer volume.
There's 90 comments on this thread at the moment. Maybe like 5 are discussing anything about the article itself. The rest are just totally predictable and generic comments, which is something the comment guidelines specifically ask to avoid. (And yes, I'm now also participating in that.)
Now, fair enough. Maybe there really is nothing to be said about the concept of the product. There's definitely not much to be said yet about the execution given nobody here will have been able to use it, so that definitely limits the scope of meaningful discussion to be had. But since the spam won out, we'll never find out.
If there's nothing of substance to talk about, we could just talk about nothing and let the obviously boring and uninteresting submission die in silence.
And if you need to warn your family and friends not to use this product because you think it will be cancelled too soon, you'll probably reach them more effectively via methods other than HN.
