I expect we will soon start to see blanket bans on fair use licenses also. At least the functional software license referenced here. There is just too much great area and potential legal risk.
Sentry's experience suggests otherwise, as 10,000+ users from hobbyists up to FAANG companies have been using Sentry under Fair Source terms for five years now.
