No one that works in the industry is going to drop Adobe, because thereβs no other functional alternative that offers an even remotely similar feature set. A lot of the files I get from clients are .ai (Illustrator) or .indd (InDesign) files, and I have to use the appropriate programs to open them, and the most up-to-date versions of those programs, or else I end up missing parts of their files.
Users that are 100%, fully independent donβt have to worry about any of that. But those people are rare.
