A little melodramatic don't you think? Aren't there much bigger fish to fry than a modest jab at the authors misuse of the word?
I couldn't care less about whether they proofread their copytext. Hell, it's probably good that they didn't spend money on any professional design work on their page, it contributes to the affordability of the product.
Basic mistakes like that make it look like unreliable amateur work.
If you can't find anyone to help you proofread, pay someone. And I'm from a third world country, I know paying people might be expensive. But in the case of some basic copy like that, a $5 proofreader from Fiverr would be enough.
It all depends on context.

I'm already thinking of all of the things I can adapt this platform to do for me.
