Municipal offices that turn to FLOSS for IT often encounter documents from external sources using that other OS and its office suite.
“in effect, administrations that do not use open standards are working against those that do”
This is one of the main tools of Wintel, perpetually prompting users of IT anywhere on the planet to upgrade to Wintel’s latest combination of hardware and software for no real benefit except enriching Wintel.
The solution, of course, is not to pay “forever” for upgrades but just quit the foolishness and do whatever it takes to be rid of M$’s influence on IT. If local governments all switched to FLOSS the “problem” would be gone overnight with very little effort except converting the existing stack of documents which is not getting any shorter by staying with Wintel.
It would be perfectly reasonable for governments everywhere to fix a deadline for the last document in a proprietary/non-open standard document to be accepted by employees and outside agencies. Just say no!
