While I fully agree, there's somewhat of a chicken-n-egg problem here though, because part of the profile shows contributions to other projects/repos, and that's more of a github thing, partly because their profile is designed differently to focus on that, and partly because there are just many more popular repos on github to begin with, so to contribute to those, an Atlasssian bitbucket profile doesn't help much, IF the primary intent is to 'show off' activity. Personally, I couldn't care less, I very much like the fact that Bitbucket offers free private repos, and I also prefer the tooling and cleaner UI of Bitbucket over github's.
