Regarding question on the thread title, i don't see Bitcoin Core developer increase block size limit to ridiculous big number[1] or add stealing confiscation feature[2]. So my answer is no.
The Core devs have already increased the data size limit to a "ridiculous big number" to more than 1000 times the previous limit.
That is more than enough to do permanent damage to bitcoin's long-term security while destroying community trust.
It is exactly the same big number as BSV so they have made Craig Wright very happy.
They couldn't do it with the blocksize so they did it through the op_return.
There is more than one way for bad actors to do damage to bitcoin.
And I would not be surprised that a future Core upgrade would include blowing
open the block size limit as they have now done with op_return.
More disturbingly they rammed through the changes out of the blue without consensus or community feedback.
The precedent has been set. They are dismantling bitcoin's sound money principles one unilateral,
centralized upgrade at a time. You can't have sound and secure money with such serious vulnerabilities.
