How do you mention you can play multiple audio streams at the same time and then claim the OS is designed to let only one app access an audio channel / device? Which one is it now? Let's dig a bit deeper into this:
Also, let's not blame everything on the OS vendor being malicious. In most cases, playing multiple audio streams simultaneously would be annoying. In android, you can absolutely play multiple sources simultaneously, and Android will mix everything together and play it.
That being said, starting with API level 31, Android actually started to enforce a concept called audio focus at the system level. That would be around Android version 12. Audio focus is basically a token that can be requested and handed from app to app, and only the app holding the token gets to talk, everything else is faded out.
I'll agree that enforcing this and not making it configurable for the end user was a pretty dumb move, but that was simply a UX decision, not certainly malicious.
If your phone is rooted, you can work around it, e. g. via an xposed module.
What I don't understand: if you look at the lab reports posted by the vendor, it will mention that it contains no alkaloids:
a) Why the hell would you buy this stuff, from a company callef "Shruumz", if it does not contain, e. g. psilocybin / psilocin? Best case, the product does absolutely nothing and you have been duped. Worst case, it does something, but based on a completely different substance / synthetic compound that you know nothing about.
b) If you get a lab report and test for amanita analytes, why is the test profile so narrow? Obviously, a different lab found something after the edibles turned out to be a huge health risk.
Even better, when I opened the lab report for a random product, all it had was results for cannabinoid testing, finding absolutely none - incredibly surprising for a product marketed as shroom edible. Why would a consumer expect or even be interested in cannabinoids in such a product?
Just a shitty company with highly shady business practices. People, don't buy edibles with research chemicals or analogs.
