Expect problems with your beta software. This means you never do anything critical with it like write your great novel on it, not unless you save and backup your novel on another storage drive at regular intervals. You are expected to report problems with your beta software. Yes, I know how odd if not downright stupid it is to PAY for beta software. It wreaks of 'marketing moron' syndrome to me.
Beta testing is already an act of altruism.
All beta testers are expected to fill in reports to the company providing the software so that it can be improved in its next iteration. Show them you care, and what you care about. If you want the Control Strip back, then say so. Let software developers who write applications for your beta OS know that you are taking your testing duties seriously and want the full functionality of native versions of their software. Let every software developer know that having their program run in Classic mode is not enough.
