Curious, how much localizationis the software/service industry in CN? Like if suddenly, Ad0be, Micr0s0ft etc got banned by U.. S to do business in CN?
Those generic commercial software are all replaceable with open source or you can just spin up a team to build a similar product in quick fashion. The Chinese has accrue enough buisness practices in all industries in the last 2 decades to reproduce the enterprise software like salesforce or oracle erp etc Them leaving China would actually help opensource and the local software industry.
The ones that are hard/difficult to replace are the ones for niche industrial and scientific purposes like the chip design software which some has already been gimped or ban.
