    What a confused image.

    1. TiVo complied with the GPLv2 and distributed source code for their modifications to Linux. What they did not do was distribute the cryptographic keys which would allow TiVo customers to run modified versions it on their TiVo devices. This is what motivated the so-called anti-tivoization clause in GPLv3 (the “Installation Information” part of Section 6. Conveying Non-Source Forms.).
    2. Linux remains GPLv2, so, everyone today still has the right to do the same thing TiVo did (shipping it in a product with a locked bootloader).
    3. Distributing Linux (or any GPLv2 software) with a threat of violence against recipients who exercise some of the rights granted by the license, as is depicted in this post, would be a violation section 6 of GPLv2 (“You may not impose any further restrictions on the recipients’ exercise of the rights granted herein.”).

    17 × 59 = 10003

    you’ve got an extra zero in there, and you forgot the 1, but the rest of your divisors match my crude brute-force approach:

    >>> n=31521281
    >>> d = [ x for x in range(1,n//2+1) if not n%x ]
    >>> d
    [1, 11, 17, 59, 187, 649, 1003, 2857, 11033, 31427, 48569, 168563, 534259, 1854193, 2865571]
    >>> yours=list(map(int,"11+17+59+2857+11033+534259+1854193+2865571+168563+48569+10003+31427+649+187".split("+")))
    >>> set(yours) - set(d)
    {10003}
    >>> set(d) - set(yours)
    {1, 1003}
    >>> sum(d)
    5518399
    

    same conclusion though: 5518399 also ≠ 31521281

    bonus nonsense
    >>> isperfect = lambda n: n == sum(x for x in range(1,n//2+1) if not n%x)
    >>> [n for n in range(1, 10000) if isperfect(n)]
    [6, 28, 496, 8128]
    

    (from https://oeis.org/A000396 i see the next perfect number after 8128 is 33550336 which is too big for me to wait for the naive approach above to test…)

    more bonus nonsense
    >>> divisors_if_perfect = lambda n: n == sum(d:=[x for x in range(1,n//2+1) if not n%x]) and d
    >>> print("\n".join(f"{n:>5} == sum{tuple(d)}" for n in range(10000) if (d:=divisors_if_perfect(n))))
        6 == sum(1, 2, 3)
       28 == sum(1, 2, 4, 7, 14)
      496 == sum(1, 2, 4, 8, 16, 31, 62, 124, 248)
     8128 == sum(1, 2, 4, 8, 16, 32, 64, 127, 254, 508, 1016, 2032, 4064)

    it’s the same joke as “caesar salad was invented by julius caesar”

    Except it’s a bit different because the Caesar in Caesar salad (named after chef Caesar Cardini) is actually spelled the same way as Julius Caesar, whereas Neapolitan (meaning of Naples) is not related to the name Napoleon at all.

    It hadn’t occurred to me that Neapolitan ice cream might have something to do with the name Napoleon before I saw this meme; the similarity of the words and incorrect implication that they are related is what makes it funny.
