Note that both Bluepill and ESP32 can be programmed in the Arduino IDE, using the Arduino library, and the vast library of Arduino sketches and 3rd party libraries (as long as they don't use AVR assembly language.
So can the Pi Pico, the Milk-V Duo (one 64 bit Linux core, one 64 bit microcontroller core), and many others.
While that is true, both Espressif and the Pico have their own SDKs, and they're really well written too.
The Arduino SDK is the simplest to use, sure, but the Pico framework (I don't have experience with the Espressif one) is extremely good, and the Pico's PIO is a godsend. I used it to implement 3 wire SPI (data bidirectional on the same wire) at almost 'real-time', which is to say, at half the speed of the hardware SPI controller (half the speed because the interface clock is put up one cycle and down the next; this also gives enough time for data shuffling).
Why does the Arduino SDK necessitate a huge markup on Arduino boards, when $0 of every computer I buy to run Linux on goes to GCC?
Just because most of the free software ecosystem relies on unpaid volunteer work does not mean it is a desirable state of affairs, especially with billion dollar companies building on top of said work while hardly contributing anything back.
While that is true, if Espressif and the Raspberry Pi Foundation can build their SDKs and still offer cheap chips/boards, so could Arduino.
I'm not expecting a $0 markup, but Arduino prices are simply unreasonable for what they offer, especially if you live in a lower income country.

Branding power. Precisely why brand drugs continue to make money over fist for pharmaceutical companies even after patents expire.

Generics may have the same active ingredient but (vastly) different pharmacokinetics - i.e. different absorption rates/retention in the body. For basic stuff such as painkillers that's one thing, but for more sensitive medication such as insulin, antidepressants or anything related to the cardiovascular system (heart rate, blood pressure and clotting) one has to be very careful when switching between brands.

Its relevant, however, that the Bluepill and ESP8266 cores for Arduino were originally independent reimplementations by third party hobbyists, not made by Arduino. And Espressif themselves have always developed the ESP32 Arduino library implementation. They weren't completely freeloading off Arduino's work, and Arduino (the company and the ecosystem) heavily benefit from contributors of all sorts. Particularly in the case of Arduino and Espressif, they have been successful together.
