It's important to honor the GPL here because these are the terms that the code was licensed to TikTok under. By violating the terms of the license, TikTok forfeits their right to use the code.

This is intended to protect the freedoms of the whole world, more or less. The GPL is intended to make software free and open for everyone, regardless of what their purpose of using the software for is. Free, Libre, Open Source Software is very valuable at this point, and the GPL generally mandates that you contribute back to the pool of FLOSS if you seek to benefit from it, making FLOSS even more valuable for everyone.

There is nothing forcing a company like TikTok to use GPL'd code in their software. Lord knows they have enough money to engineer a similar solution from the ground up, but they chose to use GPL'd code so they need to play by GPL rules.
