If you want up to date office stuff your only option is the web version, and if up to date doesn't matter to you you might as well switch to something that runs natively since you'll have to deal compatibility issues anyway.
I haven't tested it, but I have heard that the web version doesn't even have very good compatibility with the local version which seems like it should be a focus for Microsoft considering a lot of people are paralyzed by the switch to Linux due to compatibility issues with only a select few apps, Ms office being one of them.
I could be wrong, but it seems like they are already to this point.
I think this falls into the realm of "what are they going to do about" the only power block that cares about those ip's are the na-eu group, which after the play for global dominance will become a rounding error to them. The emissions may bite them, but it won't be from other nations, I have no doubt they'll keep polluting until the problems actually manifest, basically every unchecked government in history doesn't play proactively when it comes to environmental issues.
