Honestly, in my experience most the "good" PHP jobs tend to end up in the start-up space, where pace of development/sheer ability to get stuff done (PHP's strengths) are the primary drivers. As you move to bigger companies, more specialised languages tend take precedence as they can afford the increased dev time in order to achieve greater efficiency/throughput.
I still love PHP, as I like solving problems and pragmatically PHP is really really good at that. But at the end of day, everything is a trade off, and the trade-offs of PHP don't make sense everywhere.
In terms of bigger places, facebook still hire plenty of PHP devs, Slack as well - or at least they used too. Bumble (and the network of related sites) was heavily PHP a few years back too. Etsy you already mentioned. Quite a few "non-php" places still have a fair PHP estate that needs looking after too, even if they are slowly migrating away from them.
