  In a recent paper [2], Chang et al. have proposed studying "Quantum
$\mathbb{F}_{un}$": the $q \mapsto 1$ limit of Modal Quantum Theories over
finite fields $\mathbb{F}_q$, motivated by the fact that such limit theories
can be naturally interpreted in classical Quantum Theory. In this letter, we
first make a number of rectifications of statements made in [2]. For instance,
we show that Quantum Theory over $\mathbb{F}_1$ {\em does} have a natural
analogon of an inner product, and so orthogonality is a well-defined notion,
contrary to what is claimed in [2]. Starting from that formalism, we introduce
time evolution operators and observables in Quantum $\mathbb{F}_{un}$, and we
determine the corresponding unitary group. Next, we obtain a typical no-cloning
in the general realm of Quantum $\mathbb{F}_{un}$. Finally, we obtain a
no-deletion result as well. Remarkably, we show that we {\em can} perform
quantum deletion by {\em almost unitary operators}, with a probability tending
to $1$. Although we develop the construction in Quantum $\mathbb{F}_{un}$, it
is also valid in any other Quantum Theory (and thus also in classical Quantum
Theory).
