Privatization seems like a really bad idea to me. Helium is non-renewable resource. Privatization is about being 'efficient' at maximising profits. Do you think the people / companies that own the helium reserves are going to be interested in keeping helium available for centuries in the future? I'd say probably not.
For a profit based company, the only motivation to preserve the helium for future use is that maybe it will be worth a lot more money in the future. But there are two big problems with that. Firstly, the timescale is likely to be too long for the profit to be of interest. And secondly, the main reason the price would go up is scarcity; and that scarcity will come sooner if the helium is wasted in the short term. (Unless one company actually has a monopoly on helium, in which case they can create artificial scarcity by just not selling it. But that would obviously be bad for other reasons.)
I use to follow a subreddit called /r/degoogle, which was nominally for conversation about how to remove and avoid using google products. ... But I ended up leaving because in pretty much every thread there was a whole lot of posts shitting on any and every suggested alternative, mostly for not being hardcore enough. It was as if the only acceptable approach was to never use any electronic device ever again. Firefox of course was constantly under fire for taking money from Google; which apparently made them worse than Google themselves. ... Anyway, I strongly suspected that people were deliberately trying to destabilize the group so that it couldn't grow or become functional. I had no other explanation for how counter-productive the bulk of the conversations were, and it would certainly be an easy and potentially useful group for pro-google people to target.
I'm less convinced that it is happening here though, but I'm certainly more suspicious of it after that experience with /r/degoogle. I reckon probably why we see a lot of any Mozilla stuff here is just that the audience on Lemmy is very interested in what Mozilla is doing - and negative news always gets more traction than positive news.
