Assuming business user features and SLAs + deep integration with all of your google workspace are worth the additional $10/user/mo, doesn't sound that bad for a "today" price and until someone undercuts this.
I think they're actually either signaling they think Bard is less good than ChatGPT with this pricing, or they really wanted to undercut ChatGPT enterprise as early as possible, because althought I haven't seen OpenAI's private pricing I doubt they'd be selling for under $30/m, and you'll have way more work trying to piece together plugins and paying 3rd party vendors to replicate "summarize this google drive folder for me into a slide deck" type stuff.
