unless you want to know how many drain covers you pass, farts you do or seagulls you see then you might need to join the strava collective.
There are a lot of reasons for using Strava or RWGPS other than measuring performance, drains, farts etc.
I use it as a daily record of where I've travelled (touring). Adding pictures is child's play, notes can be added too.
I wish I had known about that (free) feature when I first started riding.
It's also useful for simple record keeping for consumables like chains, cassettes etc.
In strange places they can be useful for finding routes that locals use.
Your derision and disdain is misplaced, I believe
