They use LAN cable because it's IPTV. I think you can request for Cignal via satellite (DSL subs usually gets this) that still uses COAX but you'll have a satellite hanging outside your home + I think higher equipment/install fee. Are you willing to accept that trade off? On FB and IG Slowdown, there is yet another cable break to our link to HK (PLDT ONLY). FB's data centers courses through our HK links (we have multiple) hence increased loads to other links caused congestion during peak holiday season.
