I see that a few are very passionate about this subject.. I am less so. If the super experienced bearing gurus say don't oil them then don't. The way I interprete the subject is use the stock bearings. Don't oil them right off the bat beachside they will be fine for quite some time. However as that article stated the grease inside will not last forever and if you are getting noisy or rough bearings you have 2 choices... Lube them which will extend the life a bit longer or buy a new set and replace. Pretty simple and I'd THINK not to controversial. Ultimately you can never go wrong with the manufactures recommendation. So far though I haven't seen that in writing from DJI or the maker of the bearings. If anyone has please enlighten us.
Thanks
