Photographers often say that cameras made by Lycra and Hasselblad cameras are "poisonous". What does "toxic" mean here?

Mainly from Wuji forum. The forum of color shadow and mowgli is a gathering place for domestic photographers. There are naturally many local tyrants who are not bad at money in Wuji, so the word poison was born. At first, there were works made by local tyrants with expensive equipment, euphemistically called poisoning, which lured many people to follow suit or make similar works. This is poisoning. In addition, good photographic equipment is expensive, and there is no cure after poisoning, so we have to buy back the heart to detoxify. Slowly, the word poison became popular.

There are other words like "poison, virtue, taste, subject and learning", which are also popular based on this situation.
