The original commentor's note seemed to imply Carney was playing some sort of '4d chess' bullshit, dangling keys and then ditching something we'd always intended to ditch as a 'show' to appease the orange guy. Your response noted that the tax was put in fairly recently, and was set to kick in officially this month -- basically questioning the original guys narrative. You add in the question about wheat, which I'm still not sure where he got that.
So yes, I agree with your skepticism related to this being some fancy political footwork that's actually in our best interests, and the implication from the OP that we were ditching a tax that we'd never intended to bring in.
Your response even supports the comment that the move is objectively against our interests, and pro-US tech giant. Your optimism and "wait and see, mayyybeee", are naive. We've already conceded that tax, without getting anything in return for it, as well as any other area of internal domestic policy as there's a clear precedent now -- if it were part of negotiations, it would be getting discussed as part of negotiations, setting up an exemption for US companies or whatnot. We just handed them that item on 'good faith', with a dictator. Heck, during the election, I'm fairly sure I heard a quote from Carney about how he wouldn't commit to anything publicly prior to negotiations, because it's a weak approach where you basically give stuff away - but they did just that in this case.
The questionable bills, and general de-regulation / removal of environmental reviews, are in line with US interests at present, which are backed by tech giants wanting to take more control / have more autonomy. The continued (over) reliance on US tech services is also clearly not in Canada's best interests, given how the US has been leveraging their near monopolistic status in that realm. Many of our newly elected government officials got in on a promise of standing up to America's authoritarian bullshit, but once in power have basically complied and made similar authoritarian steps.
