Also the later posts indicates that the poster you're responding to is deceptively only counting non-embedded outputs as segwit. Of course those aren't common-- they're not universally supported, so if you want people to pay you you don't generally use them yet.... p2sh embedding exists because it took years until everyone could reliably send to p2sh addresses... So segwit was introduced without a new address type to ensure it could be used instantly by anyone who wanted to use it, and so unsurprisingly that's primarily how its being used. (Later-- only after segwit was deployed-- a new address type was also created for the extra benefits it provides.)
To me it's becoming a little hard to swallow franky1's extreme dishonesty. Saying segwit adoption is low because a new address type specified a year after segwit isn't yet being that widely used in the face of almost half of all transactions using segwit and continuing to argue it after being patiently corrected isn't just an honest mistake.
