To my understanding (correct me if I'm wrong) is more in relation to interviews and maybe tweets which maybe why they stopped that. Although Medirecycler has tweeted so don't know what to make of that. I don't value their tweets anyways. PRs can be done during the quiet period. https://www.investopedia.com/terms/q/quietperiod.asp
If you want to say PRs are not allowed during the quiet period, then we have a problem again. Seems like the PR on March 22nd would break that 4 week quiet period.
