Okay.
First off, afaik, they never advertised “lifetime” warranty nor software support on their website.
Secondly, as I told you in the previous comment already, you can still use the product as is! This is no different from phone manufacturers dropping software support after 2 or 5+ years. Not to mention this probably only affects hardware that are older than 2009. That’s over 10 years of software support already. Granted they could have reuploaded a version without the AAC codec, but still.
Third, looking at Via’s AAC FAQ, license fees are due on “per unit” sale, and the term of the license is five years, with additional five years renewal. There never was a lifetime license for it. The same goes for every single hardware/software sold that has AAC encoder/decoder built in. So if your actual issue is with that, take it up on Via and the patent holders, and start using foss audio codecs like OGG Vorbis or FLAC.
A pair of Stardew Valley pendants from Etsy is probably more meaningful than diamond rings, tbh.
