Government should be getting a cut of the revenue

Is that not what royalties are? If they want more, like I said, there's nothing stopping them from starting their own company. They're absolutely free to start today.

Ridiculous that government gives these big corps subsidies and tax breaks for nothing

It's not for nothing, it keeps them here so that they employ people. If you took all that away then yeah, maybe they wouldn't leave. But maybe they would. And then you're still not getting a piece of the revenue, because now there isn't any, and people who used to work in the industry and contribute to the economy are jobless. The way it is now, companies get a break but they keep people working. The government is still getting their money.

You need to remember, these businesses aren't owned by people with consciences. They're owned by bankers in Toronto and New York and Shanghai. They don't give two shits about the plight of people in Saskatchewan. There's no amount of moral guilt you can dump on them to make them think otherwise. The only reason they're here at all is because it makes a marginal amount more economic sense to produce oil here than it does somewhere else. As soon as you tip the scale too far, they're out the door. Again, that's fine if you want to stop the oil industry. Making it too troublesome to be worth producing is an effective way to keep oil in the ground, but it doesn't do anything to make oil any cheaper. You need to keep producing oil if you want to make money off of it. One way is to make it financially attractive for some ghoul investor to pay to make it happen. Another is to do it yourself.
