No Hard Feelings Davide Borsatto. It’s not personal at all. I love WordPress and I am also a full stack LAMP developer, working in Laravel and Symfony too.
The problem is about the developer who write bad codes. You can write beautiful codes in WordPress, Drupal, Laravel, Symfony where ever you want. It’s your choice.
If you don’t like a plugin / add-on just write that. WordPress is in good shape right now. You can write your plugin in OOP way, There has no restriction.
I thought You would recommend a good opensource alternative which can only do good with manage content. I am looking forward to see some opensource recommendation instead of a premium service like Contenrful.
Thanks for your understanding!
