That’s most definitely "contributing to discussion".

They don't offer this plan in the US, which is the only place this GPM subscription is available, so it isn't relevant to the discussion, and the tone is unnecessarily hostile to boot.

Oh, GPM is US-Only? That’s seriously annoying.

I agree with you about the tone, though.

Thanks to the customer unfriendly terms and conditions, a family plan is not always an option, even if a family subscription is available in your country. In my case, I have cell phone plan with a Spotify Premium subscription included, and because of that, I can't get or upgrade to a family plan.

So it may be true that Spotify has a family plan, it's not available to all their subscribers. The situation is a bit similar to Google Hosted Domains customers who can't get a Google Play Music Family Plan: unnecessary complicated terms and conditions and exclusions.

And finally a 'deal' that existing premium members can take advantage of. Since I'm forking over £10 a month anyway I might as well pretend to have a family too.

Although I do enjoy signing up to the 3-month 99p deals and moving over my playlists each time.
