How Much Do You Value Simplicity

I've run into multiple folks who seem to treat complexity as a red flag, not just not to their taste but like it's Objectively Bad Design to use a more complex thing when a simpler thing TECHNICALLY fulfills the same BASIC purpose.

It's led to me wondering if I've just been running into a rare sampling or if it's a common opinion that Compelxity exists to be a Necessary Evil and shouldn't be seen as something for enjoying.

Edit Additional Question: For those saying they oppose complexity "without a good reason", who gets to say which reasons are good ones?
