Its talking about how strong Advantage is ... And about how hard (actualy impossible as the post states) would be to get rid of it ...
How exacly is that anyhow relevant to data, wich are only telling us how many people is using the rule? O_o I mean, i can imagine you using it as counterargument, since the stronger rule is ... the stronger must be your despite of that rule, for not using it ...
You stating that im incorrect, it should be easy for you to tell me in what.

It seem like model simple enough. O_o
I simply cant find any other conclusion ... Either Larian in the end finds out that i dont want it > i dont use it. Or they find out that im one of thousand players ... and therefore minority and they dont care.
It's not that simple. I should point out that telemetry isn't solely used for combat anyway, there are a lot more use-cases, but as far as combat abilities go, at best it can be a conversation-starter. You can see the amount (or lack there of) spells are used, so if you see for example a particular offensive ability rarely be used. Though that's where the usefulness of telemetry goes on its own, from there you need discussions, other forms of feedback or any other means of approach to interpret and process why that is.
So Larian may see that people aren't using a spell very much, but that data won't necessarily be very clear at why. There may be some fringe cases where you could argue it though, say gimmick spells like Speak With Animal. If it's used very little, perhaps the world design and monsters doesn't invite much use for it, perhaps there isn't enough use for it to be worthwhile enough for a slot, or the animals that are worth talking to, aren't that obvious that they can be/should be talked to. Though even that may benefit from some more in-depth discussion.
