He is not getting any substantial donations to maintain the scrypt code and GPU mining is pretty much dead.
It is the correct decision IMO.
Are you seriously suggesting that nobody is mining altcoins? Just because GPU mining BTC isn't profitable doesn't mean shit. Hell, even with the drop in price, Litecoin mining can still net you a couple hundred a month with just two GPUs. Also, don't many ASIC miner rigs come with their own built-in mining software? Anyway, I highly doubt that maintaining and even tweaking scrypt support that is only a thousand lines of code is so arduous as to require substantial donations, but that is his choice. Someone will pick up the slack.
cbuchner1 has his own CUDAminer for nVidia cards at the moment, so it wouldn't be too much of stretch for someone else to do a dedicated miner for AMD cards that is more optimised for them rather than a catch-all program like cgminer. I also imagine once the Scrypt FPGA miners start being released soon, more attention might given to developing dedicated scrypt miners for them as well.
Personally, I'm waiting on the development of a USB stick scrypt miner that I saw in another thread somewhere, so I don't have to run my PC 24/7 and could possibly delegate to my Raspberry Pi.
