The short version

Each has a real cost: Truecaller its caller ID database is built from other users uploading their contact books, which means a person's name and number can be listed without them ever installing or consenting to Truecaller directly.; Ventoy the repository ships prebuilt binaries that are difficult to reproduce from source, so several Linux distributions refuse to package it and security teams in regulated organisations will usually reject it.
They diverge on capability: Truecaller covers Caller ID, Ventoy covers In-place ISO boot.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Truecaller

Its caller ID database is built from other users uploading their contact books, which means a person's name and number can be listed without them ever installing or consenting to Truecaller directly.
Removing a number requires actively finding and using the unlisting tool; it is opt-out, not opt-in, so most people never realise they need to do this.
The free tier is ad-supported, and ads appear on the call screen itself, which some users find intrusive during otherwise mundane phone use.
Call recording availability depends on local law and has been restricted or removed in some regions and OS versions, so it cannot be relied on everywhere.
Regulatory and app-store scrutiny of the contact-upload model has led to restrictions or bans in some countries, so availability and feature set are not consistent globally.

Ventoy

The repository ships prebuilt binaries that are difficult to reproduce from source, so several Linux distributions refuse to package it and security teams in regulated organisations will usually reject it.
Development depends on one maintainer, so a period of inactivity leaves compatibility fixes for new distribution releases unaddressed with no second party able to cut a release.
Secure Boot works only after enrolling the Ventoy certificate through MokManager at the machine, which is a manual step at every device and is blocked outright on locked-down corporate firmware.
A small number of images still fail to boot in place and need workarounds, so a technician can discover mid-job that the one ISO they need is the one that does not work.
The data partition is exFAT by default, which means no file permissions and no journal, so a stick pulled during a copy can corrupt the whole image set rather than one file.

Answered from the vendors’ own pages

Truecaller: How does Truecaller know who is calling me from an unsaved number?

It matches the number against a database built largely from other users' uploaded contact lists, plus spam reports from its user base.

Ventoy: Can I still use the USB stick for ordinary file storage?

Yes. The data partition mounts as normal removable storage and files that are not bootable images are simply ignored by the menu.

Truecaller: Can I remove my number from Truecaller if I never installed it?

Yes, Truecaller provides an unlisting search and removal tool at truecaller.com/unlisting, though you must find and use it yourself.

Ventoy: Do I need to reinstall Ventoy when a new distribution version comes out?

No. Delete the old ISO and copy the new one. You only rerun the installer to upgrade Ventoy itself.

Truecaller: Does Truecaller read my messages or call content?

Truecaller states it does not access call or message content, only caller ID and spam-reporting metadata.

Ventoy: Is it safe to use in a company that audits open source?

Often not. The unreproducible prebuilt binaries in the repository are a genuine audit finding and have blocked approval at organisations with supply chain review.
