All of this and most of what you have posted on this thread concerns your dislike of various posters or at least their posting styles rather than any exposition of why what they are posting is wrong.
Sure the pudding is not infrequently over-egged but there are several matters which are non-theoretical and not dismissable imo by the automatic cry of "conspiracy theory".
As I have said, there have been many tyre changes in the last decade which have disadvantaged opponents of Valentino's, with the 2012 mid season tyre change particularly capricious I would say, but none to his detriment of which I am aware since the abolition of the control tyre rule.
Dorna is also a commercial media organisation owned and run by venture capitalists/merchant bankers and it is undeniable that a 10th Rossi title win would be a bonanza financially for them, and garner vast extra media attention for them.
Do I personally think Dorna try to fix individual race results? No actually, but I also don't think the suggestion that they might try to slant things Rossi's way is as outrageous as you and others consider it to be.
In your earlier post you claim Rossi has now got on with it and that MM is in a position in the title race where he can afford to be relaxed, but Rossi did carry on his rhetoric in many interviews in the off-season and can similarly afford to desist now with Lorenzo's demise at Yamaha a matter of history, and MM's position as HRC's chosen one now and for a long time going forward untouchable by him. MM has also rather amply demonstrated that he is not greatly susceptible to intimidation, whatever the attempted means.
It's not about dislike of any poster in particular. I'm just pointing out that I tend not to engage when hearing the same old rhetoric, because the conversation historically goes nowhere. You yourself have often clumped together specific groups of posters here, repeatedly referring to them as "those of your ilk" ,,, so a bit of kettle/black, don't you think?
More importantly, I've already said I don't dispute the tire issue. It's all the extravagant conclusions that people jump to in the wake of the tire issue that are for the most part really stretching credulity. If there's an actual debatable fact to discuss, that's something I can sink my teeth into. There just hasn't been much of that in this particular thread. What's wrong with some of the stuff posted, is that it is IMHO, based on theories with little foundation in reality. You know the saying, "When all you have is a hammer, everything looks like nails." When I see that someone is in that mode, with an axe to grind, I try not to engage them. When they're talking about something with insight and texture, I will jump in the pool.
As to what Rossi said, in the off season, you would agree, I suspect, that much of it was fueled by loaded questions from the press who dragged it out for all it was worth. It's his opinion, for what it's worth and apparently by MM's lights, not worth much. He's self-centered and (not unjustifiably) proud of his legacy, as it were, and now he's reached the grumpy old man stage of his life and regretting his decision to go to Ducati, he's pretty butt hurt and, trying to regain what's left of his reputation, and being human, he gets stupid and lashes out; the result of which are in reality, negligible, except to those who want to re-live it repeatedly and take some kind of weird pleasure in getting all pumped up on outrage. Most of the top riders, have had their fair share of gaffs and instances of poor judgement and in some cases, dangerous behavior and if you took them one by one and added up the stats for each rider, Rossi wouldn't look quite so bad. But because he's "The Goat" everybody puts a magnifying glass over him and largely gives the others a pass. It's not unlike the Trump effect, though I don't consider them to be equally detestable. But you get the idea. For some racing is the greatest sport. For others it's a religion. Religious types always require a Devil to pit themselves against.
