Actually I like the ability to == all known ducks. There are a lot of cases that we run into like a DB that we have no control over where they use null, '' or 0 as some form of indicator of no value, it's nice to be able to ignore all of those cases when one does not have control over the quality of data coming in the pipe.

I tend to favor the mantra of be a liberal when consuming data and a conservative when exporting data and I find the == vs === does that very well. Sure it's a gotcha but no big surprise to most people that have been doing JS for any amount of time. I personally think it is a brilliant feature that save a lot of boilerplate when one understands the difference.

Obfuscation doesn't necessarily need to be hard to spot, just hard to understand. Like, could you spot this in a chunk of minified code? Probably. Would you be able to figure out what was going on? Probably not without some difficulty.
