I would not call all of them "extremely reasonable" - "forbidding reselling" also significantly discourages forking. If the original company is bought by Oracle/Broadcom, and raises the prices to unreasonable amount, all their users are likely screwed. As a user, it's pretty important for me that someone can continue to provide software under reasonable conditions even if original authors can't. (FSL and other licenses which convert to open source are much better in that regard, but there is no excuse for BSL / SSPL)
