People keep saying wp is bad. Ye it is from your point of view. But there are maybe billions who have no clue how internet works but they want a site/blog/shop whatever. Many of them don't even think about paying someone to make a website, or pay for tools.

So they pick wordpress: 1 click install in cpanel, no html, css, js, php knowledge whatsoever, pick a free theme from millions of themes, pick plugins from millions free ones, done. Maybe a bit of google to personalize it but that's it.

What do you offer devs who can make a quick 50 bucks in afternoon installing a plugin/theme, or even 100 for a quick website with admin panel and all that easy stuff?

There is a market for everyone and cms's will live one way or another. The simple & free stuff will always be more successful.
