No Apple is not going to try to make Safari compete with chrome , especially on windows.
No developers are not NOT going to use Chrome as their target browser and use Chrome push standards
Yes people will switch over to chrome since it will be the one browser developers will target for sure to make sure every hiring works. All it takes if for one website to recommend it in order for users to switch.
Ironically the only thing saving the web from complete Google Control is the opposite of competition. I do not see a scenario where competition does occur and Google doesn’t win. Especially on a service they’re not willing to put in their death bin.
