React ruined the web, and the mobile development too.

Now to load a simple website that in the past was a few kB of HTML, CSS and JS you need to download Mb of JS code. Now the browser needs to use Mb of RAM just to display a stupid webpage.

For what? It was better when we had PHP pages that did produce HTML on the server side.

Another thing to me that we have to get Meta discredit for, not something good in any way.

The web was broken long before React came along. Or have you forgotten about Angular, incompatibilities between JS engines that required hacks like jQuery, the Internet Explorer monopoly, and those who gave up on the stagnating specifications from w3c entirely so wrote their sites in Flash? Or worse, JavaApplets. Or even worse yet, ActiveX (it took a decade for South Korea to undo that latter mistake)
