  We argue that under certain assumptions the quantum break time approach and
the trans-Planckian censorship conjecture both lead to de Sitter swampland
constraints of the same functional form. It is a well known fact that the
quantum energy-momentum tensor in the Bunch-Davies vacuum computed in the
static patch of dS breaks some of the isometries. Proposing that this is a
manifestation of quantum breaking of dS, we analyze some of its consequences.
In particular, this leads to a thermal matter component that can be generalized
to string theory in an obvious way. Imposing a censorship of quantum breaking,
we recover the no eternal inflation bound in the low temperature regime, while
the stronger bound from the dS swampland conjecture follows under a few
reasonable assumptions about the still mysterious, presumably topological,
high-temperature regime of string theory.
