YouTube has no real competition. Their so called competitors are small and have crappy phone apps that barely work or they don't have any app at all like Bitchute for instance. Having a smart phone app available in the Apple and Google stores is very important as the majority of people watch videos on their smart phones and tablets as they are on the go doing other things. You severely limit your user growth if you don't have a good working app available. Another problem is the other smaller competitors don't offer streaming services and ad revenue programs to earn money like YouTube does which encourages more content creation and better quality videos to watch. People are not going to regularly post quality content if they are not monetarily compensated for it. Good cameras, video editing software and even people's time costs money. Google which owns YouTube controls 90% or more of the online advertising. You can't compete with monopoly. Advertising revenue pays for video platforms like YouTube and it's creators to operate.
