The OSS toolchains have matured a lot since then, with parts from Lattice being fairly well supported if you don't want to touch a vendor's tooling.
Gowin have some of the more interesting new parts which sit on a different part of the cost/feature curve. The Tang Nano boards seem fairly popular but I only have experience with far larger GW5 parts.
The newer parts from Intel/AMD have increasingly impressive hard-peripherals and internal features, but not that relevant unless you know what you want/need.
The CE40-HX1K iCEstick has inexplicably increased to $158 on the Lattice Store. Pretty spendy for 1280 LUTs. The Olimex Ltd. ICE40HX1K-EVB might be a good substitute at $21.

(2019). What's the latest on sub-$100 FPGAs this decade, anything significantly better than the Mojo I picked up back in 2013 to tinker with?
The fomu is fully open source, supports an open toolchain, and fits in your USB port. $50 https://www.crowdsupply.com/sutajio-kosagi/fomu
It's capable enough to run a risc v softcore
Depends on what you're wanting to do.

I think there are two interesting ways:
1. Either go for the Gowin FPGAs from China. You can get good boards for cheap from Ali.
2. There are FPGAs that now have a FOSS chain. They are very interesting too.
I just picked up this as a dev board which has an RPi mcu attached and supports Diligent pmods:

CMOD S7 by Diligent. Slightly higher than 100 bucks but it is definitely a starter's choice.
If you want HDMI, the MYIR Z-turn is just over 100.
