Is having a DevOps team wrong? No, having automation experts, infrastructure experts, integration experts, etc. all makes perfect sense. Bundling all those disciplines under a single term is what is wrong.
Is aiming to do "less DevOps" using "serverless" wrong? No, aiming to reduce infrastructure maintenance and design overhead is perfectly sane. Interpreting that as entirely avoiding infrastructure, or as affecting any of the other disciplines is what is wrong.
What we need is better work descriptions and team organizations. But while the buzzword DevOps is bad, it's not so bad to have a fancy term that executive management understands and can put some money behind - money that allows you to spend time or buy solutions to solve your actual process problems are.
