Have you considered that it might not be about money? What if the decision-makers and operators of Hurricane Electric just have certain people they just want to censor, and use their position to do it at the expense of money. Money is just a means to the end, and if they're getting to that end by foregoing money in business rather than spending it, that seems logical enough to me.
And if the government is ideologically aligned with the operators of the company, you won't find any protection from them. And in many cases it's just the government and large companies working hand-in-glove to get to their ends. Some political outsiders threatening your political monopoly? Pull some strings and have their social media accounts removed and banking taken away; but there's no recourse since "muh private company" even though they're getting direct orders from government officials.
So a good reason to be on the side of "free political speech" is that we don't want the people with the most money controlling what we can and can't say, and we don't want the government to have free reign to shut down criticism or challenges.
