And yet even 1st party lens manufacturers regularly issue firmware updates for their lenses and unlike these 3rd party lenses with USB dock they are much harder to update and easier to brick.

sorry to hear that experience .. assume you returned all copies. If you haven't, get the dock and update the firmware, it helps sometimes. I had issues with my Sigma 35mm 1.4 ART and almost gave up on them.. but found a youtube video and found that there were some screws on the 35mm 1.4 that could come loose.. it showed how to open it (simple) and I tightened them... and no focus issues now. Basically the glass wasn't aligned to the sensor due to the screws becoming loose. It's a bad QA thing, but with didn't see it in later lenses I bought. (20mm 1.4 and 150-600 C). I'm quite pleased with my results. I'd prefer canon glass, just can't afford canon L glass..

Why? So you have to return to servicing for an update to the firmware?

That statement doesn't make sense.  So you may buy an inferior product just because it may get a firmware update?  Don't get me wrong, I'm not saying third party lenses are bad.  But to buy them only because they offer firmware updates makes no sense to me.  Also, firmware updates are necessary for third party manufacturers because when new bodies are released, they have to change their lenses to perfectly adapt them.  If you buy OEM, there is usually no need for an update, or much less so.
