So first, you say that Canon sucks because they don't innovate. Now, you're praising a third party company for copying Canon's innovation. Do you wonder why people think you're a troll?
Canon sucks ... both, lack of innovation and even when they eventually innovate.. they're not making it available to their customer base quickly and in one go. But rather over a long period in ever so small incremental steps. Even when it is something as simple as e.g. Auto-ISO functionality. Or a radio-wireless flash trigger.
So, some Chinese company has to step in, reverse-engineer the Canon innovation (presumably no "rocket science" involved) and bring a product with improved and additional features over the original Canon product. At a significantly lower price.
If Canon would be "innovative" ... it would not take a Yongnuo to bring Canon customers
- Group mode on pre 2012 Canon cameras
- no (possible) hit to X-Sync for pre-2012 Canon cameras
- 2nd curtain sync over radio (though only in manual mode)
- AF assist light
- USB-port for easy firmware updates
Only feature missing in my book of desired flash functionality is direct control over zoom-reflector on radio-remote-controlled speedlites.
If Canon was innovative, they would already long ago have re-done their pre-historic and limiting wireless ETTL-protocol which inhibits 2nd curtain sync (and probably also contributes to HSS limitations). And they would be making and selling 430EX-RTs and EX-RT-receivers like hotcakes, even at inflated prices.
But they have again fallen asleep on the wheel and are being passed left and right by Chinese copycat companies like Yongnuo, Phottix, Pixel King ...
It is obvious, that Canon has become rather un-innovative, unwilling and unable to bring (even mildly) innovative products to market quickly. Not even when it would give them a strong USP, make their entire eco-system more attractive and deliver a lot of value to millions of (dearly) paying clients.
