I’m not saying that O365 is great, I use it at work and I hate it, but enterprise software has always been like this: it’s not enough to be better, you need to be something like 3x better, but if you are it doesn’t matter if you’re going up against Microsoft. Software is a lot more competitive in that way than a lot of other industries.
