I'm glad you were able to see what was happening under the hood, because this kind of thing remains hidden most of the time. And even in that case, we would want a transparency report concerning whether curation is done in a fair and responsible manner, for the benefit of the platform.

As it is now, this reveals a rather ugly side of the platform that frankly should be amended. The stakeholders are the people using the platform such as yourself (well not anymore, unless this is addressed).

The extra dtube owned account should serve solely to attract users, not to alienate them. My suggestion to them would be to let the wider steemit community curate by voting (duh...), And use the bot vote to reward those that bring in more engagement rather than try to curate themselves. Otherwise you have centralized bias that only serves to alienate prospective users of the platform.
