Of course,the public sector created a lot of the problems Uber alleviates on an individual basis but that doesn't change the fact that is a really bad solution.
Simply being correct is not the only criterion for a comment being a positive contribution to the conversation. The comment also needs to relate its new information to the topic at hand.
At a guess¹, the unsupported assertion that AirBnB and Uber have been disasters is the major problem with the comment, in addition to the fact that they are not the primary subject of the conversation which makes 'randomsearch's comment feel more like a ranting non sequitur than a substantive contribution.

...quick examples, just grabbed these articles but they're representative of the problems Airbnb has caused people and cities I have first-hand experience of:
> Uber has been stripped of its London licence after authorities found that more than 14,000 trips were taken with drivers who had faked their identity on the firm’s app.
> TfL said on Monday it had identified a “pattern of failures” by Uber, including several breaches that placed passengers and their safety at risk.

> "Short term lets are having a terrible impact. They are hollowing out communities, both in the city centre and increasingly across Edinburgh. Residents are putting up with high levels of anti-social behaviour and, very worryingly for us, we believe there is a huge impact on housing supply," said Councillor Kate Campbell (SNP), housing convenor at City of Edinburgh Council.

etc. etc.
If anything, these services make public transport more effective by solving the "last mile" problem for its users and thus obviating the need for a privately-owned car.
Airbnb is contributing to a housing crisis? You know the way out of that "crisis": Build more housing. Or more hotels, since the scarcity of hotel services is clearly what's driving Airbnb use in the first place.
The contribution to the conversation, for those it wasn’t clear to, is that regulation exists exactly because companies are prone to behave like Uber and Airbnb, and not the other way around.
Who are you trying to alleviate traffic jams for? Which group of people do you think has a greater right to traffic free car travel?
