Sure you do. You have to worry about which fork has the best chance of succeeding in the long run (and my bet wouldn't be on the one from the company that was struggling enough that it felt the need to risk upsetting the community with a licence change). You need to worry about if the new license is acceptable, and even if you aren't selling a managed service for the software, these licenses make lawyers nervous (and I suspect that is intentional). And you have to evaluate if the license change is an indication that the company no longer values the community and users.
