The range of their offerings is immense and I think each product should be evaluated individually to competition. But just as an anecdote from my company - to create a full spectrum DOCSIS signal our HW team used multiple huge FPGA chips, I think it was Altera 10 or something (device is EOS by now) and that only for the DAC (kinda), there were separate CPU, separate 10G switch, separate utility FPGA, separate memory, separate everything. And it had to be glued together with some insane mash of code on top of the FPGA blobs which not always work as expected. All in all it was a ten unit monster which used something like 4000W in steady state and a dozen of industrial coolers at max to cool it off.

And today that is replaced with a single relatively tiny in area chip (those old FPGAs were huge) from Broadcom, which does literally everything and complies with newest standard and uses tens of watts of power, and it is passively cooled. It's not quite the correct comparison since arch changed in the meantime, but if someone would build an exact replacement for that older big device using new chips and have the same specs, it would be half as big and use under 1000W or even less. And all software is ready to use without reinventing half of it manually.

But yeah, Broadcom's support is slow and opaque. and they will stall any non-major customer for month for almost any request, because they are prioritizing different tasks internally. It's like a drug dealer dependency and there is only one dealer in your town :) .
