There is counterplay, break your personality and abuse the meta

I'm pretty sure there are many people including whales who would be happy to see him get nerfed. Having to go through 10 rounds every fight is pretty obnoxious for alot of people. When they say nerf, I don't think he means nerf him to the ground where he becomes a laughing stock, but nerf him to the point where other ninjas and teams become more viable. In an mmorpg where every player is forced to purchase a ninja just to remain relevant is a problem. This causes people to lack the drive to play this game cause everyone runs the same obnoxious teams. Why? No creativity. The amount of ninjas in this game, and the unlimited amounts of combinations in the game, are all brought to not simply because of one ninja. And that causes the game to be boring, as much as it already is.

Look at the event cycles every week, you always get someone saying "Where is six paths naruto? How much is six paths naruto?" Thats how far the community has fallen. Its either you get naruto, you get taken to 10 rounds just for you to lose. Sounds fun right?

how to deal with SOSP:
- Use Rinne Sasuke to fear him so he wont scale (50/50 chance can fail horribly tho)
- Use "suppress immunity" ninjas like NY Hashi, Summer Kurenai, Ibiki, FM imprison + Edo Itachi, Habanero Kushina, GNW Madara (undodgable chase really helps) etc, etc.
- Outshield him. Using GNW Madara, Earth main, Suigetsu and Swimsuit Konan / Kakuzu can deal with SOSP (once its your team vs. SOSP, dont use mysteries, just stack shields)... works only if you have solid power on other positions too ...
- Use Ronin Zabuza to steal all attacks from SOSP.
- Use Hizuren´s reaper seal to one shot him.
- Use GNW Obito to teleport him away.
- Use Kimono Itachi to prevent SOSP from using standards (really team based, it wont work in most cases)
- Use irremovable ignite (Shisui, Konan...) to prevent healing
- Use Ashura for enfeeble to limit his dmg. (you could got him, if you were lucky)
- Use Indra to set Anxiety (you can get him by rap!ng your wallet)
- Use "immune to ninjutsu" ninjas like Edo Nagato, Hashirama, Madara edo tensei to limit dmg on your team.
- Use Edo Minato´s barrier to boost your defense greatly

Those are pretty much only ways for now, how to get a chance to beat him. However most of these require fairly stacked team (not only P1), which can be considered real at .... say 600k+?

sir, am heavy whale here. honestly I dont care whether they nerf 6p or not. But my personal point of view, they will not. Ur assumption totally wrong. This kind of game is made for money, dont you get it? Possible income sir.

I guess the solution will be an OP big spending ninja and then players will start thinking of another meta to counter that new ninja. It's the only way I can see this resolved, so if you are not willing to spend big in this game, you can never win in a Naruto SOSP match, especially against a stronger opponent...

And another solution is by deleting the game and finding another one where you will see people using not only a fragment of characters from a big pool of possibilities.
