Complexity is just another part of natural systems. It's not something to be avoided for it's own sake, in as much as we should avoid having eyeballs, because they are crazily complex. Yet we tend to like ours and find them worth whatever cost they incur. The emergent behavior of containerization has had an overall positive effect, even if it has annoying costs.
For the end user there is no positive effect. Many websites were better in 2005 and had greater uptime. They were also better organized. Ebay and Amazon were leaner and more pleasant to use.
Citation needed. There were a lot less sites, maintenance windows in the hours weren't uncommon, there was no security to speak of (SQL injections, no SSL/TLS, etc.), and sites could do maybe 1% of what today's sites can (not saying that all of it is good or necessary, bit i quite like a non-insignificant amount of those new features like native video, audio, graphics, dynamism, etc.).
