You'll avoid it, because you don't have any valid arguments.
Slow connections are not a problem, because React is ~40KB and Preact is ~3KB. If downloading 3KB is too much for your network, it's not the fault of React, JavaScript or any web developer that you're gonna miss out. Also, server-rendered HTML would NOT be smaller than 3kB - in fact it would require MUCH more bandwidth since server-rendered HTML can't be cached as easily, so every page will re-transfer the exact same HTML for shared things like navigation bars, footers, etc.!
Accessibility isn't any issue either, this is a ridiculous argument to even try to make, accessibility tools use HTML and are fully aware of the existence of JavaScript - React doesn't magically bypass HTML to display something on the page.
