There are a lot of good free video editing and creative software out there. But for someone who wants to get into the film or graphic design industry, they really have no choice but to get locked into the Adobe Creative Cloud ecosystem.
I am self-learning to be a graphic designer, and because Adobe software dominates this industry, I have to subscribe to Adobe Creative Cloud, which is not cheap! Any other software company that makes better products than Adobe will still remain insignificant because nobody will notice their innovation, since practically everyone uses Adobe software.
