Don't be willfully dense. Not all rebellions are created equal.
You do realize you're corroborating what I am saying, right?
Sometimes, you have to read between the lines, especially when dealing with Chantry propaganda. Elthina supports a coup that benefits basically no one but herself, and makes her look like a higher authority than the viscount, harbors a claimant to a neighboring city's throne, and that city's Circle conveniently burns down. It'll probably need a new, larger, Templar garrison soon, yeah? She p
romotes Petrice and does nothing to stop her from whipping Kirwall into an anti-Qunari frenzy, which seems like a good way to rid herself of some political and military rivals in the city, and gives her deniability if it fails. She does nothing to stop Meredith because she doesn't care
what Meredith does, Meredith is her dog until she goes feral.
If anything, Elthina seems to be a tyrant with expansionist aims, and probably wants the Chantry to rule the Free Marches outright (under her, of course).
Elthina was behind the burning of Starkhaven's Circle; never mind Decimus; because she has Sebastian; never mind that she encouraged him to leave if he wanted to and discouraged him from seeking vengeance for his family's murder; because Starkhaven will need a bigger Templar garrison; never mind how Starkhaven has a Grand Cleric and will need fewer Templars if there are fewer mages.
I mean...do I even need to say anything else? This is not "reading between the lines", it's ridiculous.
Everything, in your mind, is some darstadly plot by the Chantry somehow. Do you know who you sound like right now?
Meredith when she was at her worst.
"Orsino had nothing to do with this plot? That only means he hid his tracks exceedingly well."
"Elthina encouraged Sebastian to follow his own path? That must have figured into her plan somehow."
