Wow thanks dude, good find
@adlk mentioned this in slack https://github.com/meetfranz/franz/pull/587
It's not a backdoor miner.
It's a donation option that can be optionally turned on.
The button to turn it on was removed a while ago, but the script is still present. I've been using franz5 since first linux release and have never had issues relating to mining.
the optional mining feature to receive a free premium account has since been long removed!
Not sure if it was removed or even optional, noticed from time to time franz cpu and memory usage gets crazy
Franz was minning in my computer today! (11-19-2019)
