Perhaps because UK hasn't had and still doesn't have real industrial strategies. Also, too many decades, as a dogma and mantra of 'market forces must dominate policy',  successive UK government have allowed all its best IT companies to be bought by foreigners that then get saddled with buyers financial problems, profits exported, UK tax payments reduced through accountancy manipulations, pensions raided or poorly funded, etc - a loss, loss scenario for UK plc and national industrial capability?

For decades UK governments have cut industrial costs at home (with subsequent loss of jobs, taxes, indigenous capability) by exporting manufacturing capability, jobs and IPR, then bought it back (further sending uk money abroad) and becoming vulnerable to the whims and technology exploitation of foreign companies and governments.
