People are free to spend their money however they like but it does seem like you are being fleeced by paying for things repeatedly.

Fastmail just seems like a way to pay for everything you already get from Google again. Google's podcasts app is free although £10pa isn't really breaking the bank. Your YouTube Premium already includes music so why have Spotify on top?

I think the biggest one would be paying £80pa for a function the alarm app on your phone already has: set up a playlist from Spotify or YouTube of your favourite meditation tracks and have it play in the morning when you wake.
