I liked when Maya used to have perpetual license agreement where you would pay full-price for their software of that year and keep it forever. Then they ended up switching to a monthly subscription before this Adobe was newly adopting into pay-per-sub model which also angered me because I was saving up money to buy photoshop full license.The model suck! If there are competition that matches over Maya I would switch in a heartbeat just like how I switched from Photoshop to GIMP and other software that offer similar service.
I’m currently transitioning into Blender
