Those satellites are built by a for-profit organization. They want to make money by providing internet services, they don't care about science or scientific research.

Then that is potentially rectifiable.

Hope future satellites will be better off so that Radio Astronomy does not suffer.

Just some ideas based on time in the industry building satellites would be poor quality enclosures on the satellite, lack of filter pins on external cables, general poor workmanship or tolerances on electrical unit boxes meant to create faraday cages.

Poorly manufactured or designed power supplies. Emissions from the phased arrays themselves that may have poor grounding or lack conformal coatings due to cost reductions.

Lots of options to cause it. Bummer for the radio astronomers - that will be tough to work around for the foreseeable future.

Any idea how such broadband emissions come from a satellite?

While newer Starlink spacecraft have been modified to be less bright at
visible wavelengths, the new generation is very bright in the RF
wavelengths. See this article just published:
