Nothing at all. It was a poor tool that was used because the people with the proper tools didn’t do their job. But don’t worry, even if this reaches the Supreme Court and they rule the same, politicians will shrug and invoke the notwithstanding clause and nothing will happen, except for a bunch of people who were being assholes will feel vindicated.
I recently got an update on my phone where I can start recording with a tap. It does play a recording so both parties know it’s being recorded, so it would be applicable in a two-party consent jurisdiction (hang up if you refuse).
Also, over a decade ago when I was mucking about in LineageOS, I’m pretty sure there was an app you could install if you were in a one-party consent jurisdiction, which would not notify the person you were recording.
