A big part of the problem IS Microsoft acquisition. They forced them to move to Azure, which is terrible.
Around 8 years ago I was working for a company that they also acquired, and they also forced us to move to Azure. Performance was terrible and our system wasn’t just working there as it should. A few years later our service was dead and all customers moved to one of their office products.
Only backend developers that think frontend is trivial and we’re all just idiots think that HTMX is the solution. They saw it working in their hello world side project and think they discovered gold.
This is why I'm a big advocate of Inertia.js [1]. For me it's the right balance of using "serious" batteries included traditional MVC backends like Laravel, Rails, Adonis, Django, etc... and modern component based frontend tools like React, Vue, Svelte, etc. Responsibilities are clear, working in it is easy, and every single time I used it feels like you're using the right tool for each task.
I can't recommend it enough. If you never tried/learnt about it, check it out. Unless you're building an offline first app, it's 100% the safest way to go in my opinion for 99.9% of projects.
