Whoops, I meant “them taking over Trakt or Trakt taking over them.” 
In general this is going a bit off topic as we’re this topic is otherwise solved but as one last response - perhaps otherwise create another thread or using an existing thread where it’s been discussed - VIP Costs Too High?.
For the prices, I don’t know them myself, and I’m unsure it’s necessary for Trakt to disclose that but sure, most of those pricing models might be standard. Even if it was $15 or $20 per user (which seems high?), if we assume the majority of VIPs are paying $30 as of up until last year, then that still covers that completely so I don’t see the problem. The rest of the price difference has also been discussed in terms of it not changing for 9 years, plus the company expanding and paying for resources to run everything behind the scenes.
My point being: Just because the price changes happened around the same time doesn’t mean it’s completely related to Younfiy costs. But if that’s what you want to assume and focus on, I can’t stop you.
