That's a big one but FR24 isn't as useful for that nowadays as they mask private aircraft on request of the owners. Private tracking networks are more relevant now.[0] Conversely, many aviation enthusiasts are more interested in hyperlocal tracking where FR24 again loses-out to tightly-focused private networks. So it's really aiming to position itself as a (1) business solution for fleet management and (2) for general travellers who aren't concerned with watching 'special' traffic but want to see where is their delayed United flight. [0] However many of the same operators who have their aircraft publically hidden or masked also use FR24 for managing their own fleets as it's much cheaper than subscribing to datalinking through SITA or whatever.
