Uber has never once turned a profit, and is allowed to continue running their business. If you’re a small business owner running an ebay or ecom business, and you claim losses for 3 out of 5 years in a row, it’s likely that the IRS will audit you, and could deem you a hobby. Amazon is often cited as not generating a profit for many years, but is now profitable. For them, it was somehow okay to run a business making no profit! So like, how come small businesses can’t claim losses, but big corps can?
It’s hard to get a good read on these things. You’ll only see the perspective of the person that thinks they were cheated by the IRS. The IRS won’t make Reddit posts about people carrying out tax evasion.
Likewise you say the IRS dont think it’s a business. They probably carry out much stricter measures than that. Probably much stricter than the people complaining on Reddit. The people complaining also only “think” it’s a business.
