After a quick Google search I learned that the answer is “kinda”.
Just like us they do produces gases as part of their metabolism. That gas has to go somewhere. Some of it is absorbed into their hemolyph (blood) and expelled into the air through openings in their exoskeleton. But it’s very unlikely that none of that gas exits through their anus.
Also, people have spotted “bubbles” on insects trapped in amber right where their anus is, it’s likely that those are encased fart-bubbles.
That is only a good point until you remind them that the government/corporations aren’t just entities but also consist of people, any of which could end up being their neighbor tomorrow, hold their next job interview, be their next potential tinder match, etc.
Of course the rest of what you wrote is true too, but I really felt the need to point this out.
To give an example: I’m in data science. As part of a contract work I had access to a csv dump of a database of addresses of all people who ordered campaign material for a specific political campaign. I could have easily sated my own curiosity and checked who in my near vacinity is in that list, as well as the exact amounts that they ordered and some other notes about them. Suddenly it wouldn’t just be some corporation anymore but their neighbor.
