Adobe may have had massive resources, but either they are incompetent, or didn't spend any time on flash.
Multiple times, single devs working solo, wrote full flash interpreters over a few month.
Adobe just doesn't know what they're doing. Look how they cratered cold fusion too.
They also had a security / license daemon, lmgrd. What a joke, used MAC addresses for license issuance, was buggy, could be defeated with a simple ifconfig command.
