What would happen if Microsoft Office started to charge $250/mo tomorrow?

My guess is you'd very quickly get a bunch of teams scrambling to produce something to compete and capture a huge market by charging a tenth the price. Funding is taken care of when winning there is worth so much

Maybe it won't happen overnight because they're huge software suites.. but it will happen. We need regulations to take care of anti-competitive practices - but after that the market seems to work pretty well for keeping companies in check
