I'll be interested to see how this plays out; I generally support laws that protect employees from being fired based on what they say and do outside of work, but it seems like there's an obvious issue where comments made outside of work could create a hostile work environment under (eg) the CRA. (I don't know if this case in particular is anything of the sort, to be clear.) My bet is on Block settling rather than taking on a fight that Twitter/Musk will almost inevitably appeal to as high a court as will hear it.
