Exactly. To be honest I suspect they only made their encoders free to use on Android because they figured it would increase their market penetration (more aptX support on Android means more aptX-compatible headsets sold) which in turn would allow them to make even more money on decoder licensing fees (for headsets) than they would have otherwise (since fees have a "per-device" component). This move isn't for the greater good, it's for money, which truth be told they make a pretty good job at extracting from a technology that dates back to the 1980s.

Which is a shame because SBC is objectively a better codec than aptX. I'm not even kidding. Ever heard of SBC XQ? It's a higher-bitrate version of SBC (same codec, better settings) just like aptX HD is simply aptX with a higher bitrate. Funny thing is, the Bluetooth specification only suggests encoder settings up to 328kbps for SBC, so until recently no encoder ever bothered to go higher. But it turns out most headsets can decode SBC up to 730kbps. The people who discovered this came up with higher-bitrate encoder profiles, and named them SBC XQ.

And not only is SBC supported by every Bluetooth headset ever made because this is mandated by the Bluetooth specification (and aptX isn't), but unlike aptX, SBC uses psychoacoustic modeling, which gives it a better perceived sound quality than aptX for the same bitrate. The result is SBC XQ can beat aptX HD in terms of sound quality while using a comparable bitrate, and works with almost every headset in existence, even older ones. Universal support, better quality/efficiency, and no additional fees required: aptX has literally no reason to exist other than filling Qualcomm's pockets. SBC XQ has already been implemented on Linux (via Pipewire) and LineageOS-based Android ROMs, let's hope it will come to mainstream Android (AOSP) soon.

I think this would only be an impactful issue to developers. Unless you're over there going bill Nye on your personal equipment and even then the likelihood of anyone giving a crap would be like fox kicking down your door because you recorded that football game to a VHS through your VCR and you only obtained the express written consent to do so from the NFl and your local priest but failed to receive letter to consent from the blob that is Fox. And it's fox so they can straw suck butt toots ya know?
