The worst of all engines is the 2.0 and 2.4, The Theta 2. . Another model engine was the "Nu", the 1.8 and 2.0 liter motor that had this issue of destroying itself too. The 1.6 and 1.6T Gamma motor is one of their better motors. A 10 year Hyundai mechanic said "If you don't see a side of a piston skirt in the oil pan by 6,000 miles, you wont have a problem with the 1.6 and 1,6T motor." (with the exception of weak connecting rods in the 2013/14 Veloster Turbo that has been over/badly tuned...BOOM!).
The Global Engine Alliance was a joint venture between Chrysler, Mitsubishi Motors, and the Hyundai Motor Company for developing a line of shared 4-cylinder engines. The initial design of the engine block and cylinder head was handled by Hyundai. However, each manufacturer configured their variants of the initial design differently based on their needs. In 2009, Chrysler bought out Mitsubishi and Hyundai's stake in the joint-venture; however, each company retained rights to build the engines.
It was said by Hyundai, that they had an issue with leaving crankshaft machining metal scraps in the oil passageways for 2-3 years on the 2.0 and 2.4 liter motors. Well how does this correlate into 9 years of what appears to be bad piston metallurgy and bad crank and rod bearing metallurgy choice. Chrysler and Mitsubishi used their choice of piston, crank, and bearing metallurgy, along with their choice of oil pump design AFTER the disbandment of the engine alliance in 2009. After 10 + years of Hyundai/Kia beating it's head against the wall, and nothing changed with their horrendous choice of metallurgy, all coming from a world wide behemoth of a metals company. "The Irony". These 10+ years I have not heard of the other manufactures engines destroying themselves like Hyundai's have.
It has been said 14% to 16% of all Hyundai/Kia motors will destroy themselves, sometimes as many as three times in one car. Many with Hyundai OEM oil filters on them, since many privater shops will use Hyundai OEM filters to protect themselves. I don't think it is the filter. Too many live a long life with every different filter known to man.
My wife had a 2013 Elantra GT 1.8 where at 14,000 miles, and a life of 3,000 miles oil changes ( short tripper 3 miles to work) of SuperTech full synthetic and Mobil . The motor destroyed itself with scuffed and brutally galled piston skirts where the metal went into the lifters from oil filter bypass startups and took the lifters out and gave it the CLASSIC "Hyundai Tick of Death".
One of the key problems a Hyundai/Kia CAN be born with.

I now use the Fram Titanium filter because I question if the tiny holes in the Fram TG/XG that COULD create foam vs the larger easy flowing holes in the base plate of the new Titanium. Again just a hunch that I am going to go with as a Hail Mary opinion of hope. Ha Ha.
My hypothesis is, it is not the filter or the machining chips, I think it is metallurgy engine part choice. That's from my research into the matter, just my opinion.
.
I 100% agree with you on using the Fram Titanium and while we may be in the minority it makes sense to me.
FWIW I don't trust Hyundai's engineering expertise especially when it comes to things that they can save a dime on in the production line or in the parts department like with their OEM oil filter (I would say the same about Subaru's OEM oil filter as well).
*Interesting comments regarding the new FRAM Titanium oil filter (i.e. larger holes) ... I'll have to research .
