You could make the same argument with Adobe or any other PDF software. Why doesn't everyone use all use BentoPDF? Things like brand, and simply what shows up when they search on Google are factors.
Also, Bento doesn't have a desktop app a regular person can download. You have to download the GitHub. Non-developers won't do that.
Additionally, each tool is separate. It's not all in one editor. That's a UX consideration. BreezePDF, everything is in one editor interface. It added a lot of development complexity but makes the UX better in my opinion.
I tried Bento and some of their tools are very slow, cause of large downloads to the client. BreezePDF is much faster.
Good for them making an open source tool though. Lots of options out there and everyone can choose for themselves.
You are shilling your stuff at a wrong place, I think. Better apply to YC or, I dunno, go public. Also add some nice catch phrases (e.g. "Blazing Fast", "Production Ready") and emojis here and there.
