everyone can find an issue with anything if they think long enough about it. most of the negativity you are receiving is because the algorithm has paired your content with that the likes of “Sasha’s” viewers as an extreme example, which is extremely clickbait-y, divisive and anti-Trading212 (while pretending to be otherwise).
Trading212 IS a LEGIT company and platform, there is no debate there, so if anyone tells you otherwise block them and if you can delete their comment. you don’t need that ruining your YouTube experience or poisoning your greater audience. as for quality of service, there will always be a few shortcomings no matter who you choose to invest through and this will depend on where your values lay. I personally like the overall package that T212 offers and have little reason to find fault with them, there are a few minor ‘niggles’ that could be improved in my experience, but I know too much about how much work goes into software improvements and process changes to grief them over it like some jilted ex. I could fantasize about how great it would be to get X, Y or Z feature, but even should they offer it, there is no guarantee I would make use of it, it would just be comparing other brokers for the sake of comparison and little more.
this may seem a little out of place but as a youtuber, consider watching this: YouTube Employee Reveals New Secrets for Growing Your Channel... - YouTube
as your previous viewers can influence your future viewers, just keep doing what you do and what works. ignore the haters, block them and you will find that the crowd your content is being shown to will change accordingly as more data is collected on your niche and content offering. never stop being positive and factual in your approach, your audience will notice especially as most viewers will see your videos months if not years later, they will think “oh so this person has always been honest, forthcoming and consistent in what they post”.
for the record, the biggest issues came in the form of stock offerings, server response and transparency. Trading212 has made many improvements over the last 2 years tackling each of these issues and they continue to do so when more recent issues crop up. yes, admittedly there is still more that can be done, but like anything in life its a work in progress.
