Even without considering the typos, the diagram is incomprehensible with all these arrows pointing in every direction and textboxes placed randomly. I had to look at the original to understand it.

Well, that explains a lot about the product quality. Their entire development workflow is a complete fucking mess.

• Long-lived feature branches.
• Creating merge commits to main just for the sole purpose of tagging them as releases while also maintaining separate release branches.
• Force-pushing tags to incorporate post-release hotfixes instead of releasing minor patch updates.
• Taking bugfixes from releases and merging them back into the development branch (have they not heard of cherry-pick?)
• Always using merges even when a rebase would be easier to follow and keep the history more straightforward.
