ClaimsMark Zuckerberg

“Today, Linux is the industry standard foundation for both cloud computing and the operating systems that run most mobile devices – and we all benefit from superior products because of it.”

Factual Technology

Linux is the industry standard foundation for cloud computing and for the operating systems running most mobile devices.

Unresolvable The public record could not settle it.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

Judge as of 2024-07-23. True: industry data from around 2024 show Linux runs the large majority of cloud server workloads and is the de facto standard there, and that the operating systems on most mobile devices are Linux-based (Android, which uses the Linux kernel, holds a majority of global mobile OS share). Mostly true: both are broadly right but with a small qualification (for example 'industry standard' is debatable for some cloud segments, or Android's share is only just over half). Mixed: one part holds and the other does not. Mostly false: both rest on something real but are overstated (for example Linux is significant but not dominant in cloud, or Android is Linux-based only in a sense that does not support the claim). False: the evidence shows Linux is not dominant in cloud and Linux-based OSes do not run most mobile devices.

  1. E1 What's Android's market share? (updated Jan 2025) SOAX · 9 January 2025

    “As of January 2025, Android has a market share of 72.15% versus iOS, which has a market share of 27.37%”
  2. E2 Market power – supplementary framework and evidence UK Competition and Markets Authority · 6 May 2026

    “Overall, the measures suggest that Windows Server has a significant share of the server OSs used on-premises and a moderate share of the server OSs used on the cloud.”
  3. E3 Market power – supplementary framework and evidence UK Competition and Markets Authority · 6 May 2026

    “This data shows that Microsoft’s share was high at [60-70%] in 2023. It has been stable at this level for the period we have data for (2019 to 2023). Linux’s share in 2023 was [30-40%].”
  4. E4 Linux adoption Wikipedia Own record

    “Although based on the Linux kernel, Android has very little in common with the conventional desktop Linux software stack predominant in most Linux systems.”

Reasoning

The evidence supports the mobile part: Android, which is based on the Linux kernel, holds 72.15% share [E1][E4]. It does not show Linux running the large majority of cloud server workloads: E2 describes Windows Server's cloud share as moderate, and E3 gives Linux 30-40% against Microsoft's 60-70% without saying which segment or measure that covers.
