Conspiracy theory noted.
cxwrench mostly sees bikes that rack up thousands of miles in a year. If you have bikes that only log 500 miles in a year, then every year would be excessive. If 2000 miles or more, cables once a year would be prudent. 5000 miles a year or more and you should probably replace housings as well as inspect under bar tape for handlebar corrosion. You don't want this to happen to you:
Bikes are always stored in a garage. Since I live an an area that has a winter season and snow on the ground ~November thru April each year...What bike I ride depends on the weather/season. ~April - October my hardtail, full suspension MTBs and road bikes are used. ~November - March is strictly fat bike. Between all of them I average about 4000/miles a year biking.
