For future reference
It's not like I don't think Muse Group can be good stewards for Audacity, but the following tweet is one of those clear cut, no excuses tweets that unfortunately don't always hold up in practice, so I'm documenting it here for future reference. Link to Tweet.
There will never be a single ad in the Audacity application., ever. It will always be open source and will remain 100% free, forever.— Muse Group (@musegroupbrands) May 5, 2021
