Not really. Enshittification requires high switching costs, so users stick around despite thinking "yeah I should go somewhere else". With Audacity, switching costs are low. You either can compile the thing with the relevant features disabled, or you can just download an older version of the software and stick with that to the end of time if you dislike the changes a new version brings.

Even to the suitiest of corporate suits it's clear that the enshittification funnel (first it's awesome for users, then for partners like publishers and advertisers at the cost of users, then it's awesome for making money at the cost of everyone else) simply doesn't work with an open source program.
