hah!I just looked through and there are about 600 web apps supported. You really don't use any of those? Amazon, Gmail, Dropbox, Google Suite, iCloud, Messenger... are you hanging out on Hotmail and ordering online from Target while storing all your files on a backup thumb drive?
amazon - nope, gmail - nope, dropbox - no, google suite -no, icloud - yes but its integrated in mac... messenger - not really, maby occasionaly.
email - private domain / server / via mail app
order online - multiple e-shops, dont live in US
file storage - synology NAS.
.. so for me from this list it is a nope.
people do different things really.
