Perhaps, but I also see 2e as having created grognards partially as the fallout from Gary's departure from TSR, and partially a reaction to bad modules and some of the design decisions in 2e. Also, 2e wasn't a big enough change that some groups saw it necessary.
Some of the 1E AD&D grognards I knew from that time period (ie. 1989-1990), were the people who thought 2E AD&D was purely a cash grab. They completely refused to participate in it under any circumstances, and stopped purchasing any new TSR products. The only TSR stuff they bought ever since, was mostly older 1E AD&D and BXCMI D&D modules they didn't have previously.
