Yes, it is really a thing. It is HORRIBLE to many of us, and it has been discussed and complained about ad nauseam in many threads. But you do have the ability to call TiVo and get them stopped after you begin seeing them. But more importantly, in regards to your Roamio problem, you absolutely do NOT need to buy a new TiVo if you want to keep using it. Totally simple for you to buy a new drive for about $60 and just swap it for the existing one - plug and play, nothing else to do except plug it in (assuming you do not want to try and save your recordings).
