To be clear, I'm not assigning blame; we create enough of our own bugs 🙂 but it is a working reality that a portion of our support volume is caused by code that is not ours. We have added tools to speed up the debugging but it's not always clear that a third party app/hook is the problem.
There's a lot we can do of course but our problem is just people-hours. We make a loss on the marketplace currently when you factor in battling fraud, chargebacks, as well as debugging support issues. We are OK with that, but it does mean that we do not have a lot of resources to put into it beyond what we already do. I'm also not entirely convinced there's a pool of younger newer coders who would be willing to learn our framework and develop modifications. The problem isn't so much that people are leaving the marketplace (life changes, etc), it's that there's fewer to replace them. Part of the barrier is the cost of course, and I do recognise that but also PHP isn't a "cool" language anymore. Most developers are learning javascript (node, react, etc). This is why our future efforts are in building APIs, events and triggers that JS languages can take advantage of.
