The problem with office suites is that they have a niche market. Howso?
Well anything business-related will use MS Office 9/10 times. College students and any home use >25 will use Google Docs 9/10 times. Professionals will use professional-grade solutions as have been offered itt. This leaves a very niche market for non-MS office software, namely freedom-minded (as in speech) college students (who are probably on the broker side of the average college student) and freedom-minded (as in speech) authors (again, not the richest people on earth), and finally free-minded (as in beer) individuals who don't give a damn about ones rights. None of these camps are likely to donate to projects, or (aside from maybe college students) be devs who will contribute.
/tech/, whatever that means (I assume you mean the majority opinion of this board?) may not like libreoffice because it's a copy of MS-office, with which Microsoft created a market to sell their product to. If it wasn't for MS-office, chances are we'd all know LaTeX and wouldn't be having this conversation.
