Faster wi-fi ... as long as you use our routers, our phones, our tablets, etc?
I suspect not, more likely they will share their implementation of 802.11ac firmware with whatever they have in their access points already. Which is standard conforming and works well with all types of devices, nothing proprietary here. However good (or bad) implementation can greatly impact actual achievable throughput and latency, simply because these two are tied to timing, which itself is tied to performance of the code itself (i.e. the standard is quite forgiving because it has to, but the implementation can aim for the best performance)
FWIW I do have some networking kit from TP-Link (e.g. CAP1750 access point, some managed switches, wifi controller etc) and it is good piece of kit - or excellent if you look at the (very small) price tag. They do not spend money on fancy features or loud marketing, and sometimes the hardware may be less robust (looking at old "nano" powerline adapters ...), but it is refreshing compared to Netgear, D-Link, Linksys etc. usual suspects.
