It is very hard to avoid when you have Vercel doing partnerships with SaaS cloud providers that end up supporting only React and Next.js on their SDKs.
Even if other programming stacks are supported, they tend to be 2nd or 3rd class versus anything React.
Look into the ecosystem of headless products that have jumped into the whole MACH architecture hype cycle.
Then you have to justify to upper management, and partner support when problems arise why you are not using their SDK.
Why on earth would your cloud provider dictate your front end stack? My mind is in tatters trying to understand this thought process.
