You can't when against these people and I highly suggest ignoring these "consumer rights" people as their opinions don't reflect what makes actual business sense to do.
It makes a lot of business sense to scam people. There's a lot of money to be earned doing that. That doesn't make it a good thing.
And the whole app part specifically criticises the fact that while there is an option to read put some information via the web, you don't get to read out everything there and there's no valid reason to do that. They already went the extra mile so you can read some stuff via the web, so having some stuff that you can only read via the app feels malicious to me.
I think generally reading this felt like a review of stuff that wouldn't be criticized in a YouTube Review for example, but that I personally do care about.
