It's just common sense -- unless you genuinely believe Core developers have more financial stake in Bitcoin than miners or exchanges, which would be a bizarre assumption, as far as I see it.
Common doesn't necessarily mean correct. Many of the larger 'miners' are owned by disinterested investors, and managed by hired managers that have very little interest themselves-- or, most commonly, aren't actually miners at all but are selling hashpower to pools with little capital investment and often extensive investment in bitcoin competitors. Some of the largest hashers have never even used a Bitcoin wallet-- I've talked to people who owned significant percentages of the network hashrate that just mine with
theira pool paying directly to an exchange account, and for years I had a pretty good business selling options to several large hashers so they could reduce their Bitcoin exposure
even in just the 100 block maturity window.
Similarly, many exchanges are predominantly invested in Bitcoin competitors, and spend a lot of resources promoting altcoin-of-the-day to anyone that uses their services. I had the CEO of one of the largest exchanges tell me flat out that he'd make a lot more money if bitcoin died (and wasn't I stupid for not being invested in ethereum).
This is in comparison to bitcoin contributors who easily can have 99% of their net worth as Bitcoin as well as their professional reputation and ability to work tied up in Bitcoin, the same people are also sometimes miners themselves and involved in the ecosystem in other ways. Absolutely there are miners (especially midsized ones) that have their necks on the line, but even though have significant short term cash flow pressures that can be very misaligned with Bitcoin's success. The capital expenditures of miners are also rapidly deprecated and their primary cost is *power* which can be turned off at any point. You can just look at all the inscriptions flood for example of how miners are easily somewhat misaligned with Bitcoin's long term success (or log into any of the larger exchanges for a very IN YOUR FACE example of the current massive misalignment).

Banning those who are critical of the PR from github isn't bad conduct to you?
Well that's one way to shut down the debate when you know you have no credible argument.
Who is banned from github? What debate
itis shut down? Also what relevance does this have to you failing to read the existing discussion even here and wasting everyone's time with confused arguments as a result?
