As someone who has been a big Brady supporter post-Pats, I also agree it was a dumb move on Brady's part not to mention the Pats (especially his former teammates and the fans). Someone on his team should've pushed him to take the high road, which he has consistently done since leaving the Pats up until this point. I'd be lying if I said it wasn't annoying to me. But at the same time, it's such a small thing that I'm not changing how I feel about him in any material way - I'm incredibly grateful to have to seen his career and will be an advocate for his legacy forever.
I also still think it's likely he will have some kind of acknowledgment for the Pats organization, Bill, his former teammates, and the fans in the days to come. This is ultimately just a small PR gaffe that nobody will remember in the long run.
I'm also annoyed with Bill not putting out a statement, and his case it's added to a longer history of petty behavior. As fans, we love both of these guys and naturally just want "Mom and Dad" to get along again so we can all bask in the (shared) glory without any negative feelings or feeling like we need to separate into camps post-divorce. It's ok - I am still confident it will get sorted out in the months and years to come.
