Which company has done ARM development right?

I don't think the manager who mentioned this to me meant anything derogatory about Malaysia but rather to make it clear SoC FPGA's were not something Altera had any great interest in and did not closely monitor the tool development. They found a cheap place to outsource it and washed their hands of the matter.

Altera (ie PSG) revenue has actually been going up, but it appears to be all data center. To a company as large as Intel, the revenue from the other markets is probably just not worth worrying about. Intel just seems geared towards large expensive chips and always seems to fail on the lower end.

I tried Microsemi SmartFusion. It's ok, but zero support and the tools are rudimentary (that was 3 or 4 years ago, so may have changed).
